The -.Va ar_size -field of the header (see below) will then hold the sum of the size of -the file name and the size of the member. -.It SVR4/GNU -In the SVR4/GNU variant, names up to 15 characters in length are -stored directly in this field, and are terminated by a -.Qq / -(ASCII 2FH) character. -Names larger than 15 characters in length are stored in a special -archive string table member (see -.Sx "Archive String Table" -below), and the -.Va ar_name -field holds the string -.Qq "/" -followed by the decimal representation of the offset in the archive -string table of the actual name. +.Xr ar 5 +format only supports a limited number of attributes: the file name, +the file creation time stamp, the uid and gid of the creator, the file +mode and the file size. +.Pp +Archive headers are placed at an even byte offset in the archive file. +If the data for an archive member ends at an odd byte offset, then a +padding byte with value 0x0A is used to position the next archive +header on an even byte offset. +.Pp +An archive header comprises the following fixed sized fields: +.Bl -tag -width "Li ar_name" +.It Ar ar_name +(16 bytes) The file name of the archive member. +The format of this field varies between the BSD and SVR4/GNU formats and +is described in more detail in the section +.Sx "Representing File Names" +below. +.It Ar ar_date +(12 bytes) The file modification time for the member in seconds since the +epoch, encoded as a decimal number. +.It Ar ar_uid +(6 bytes) The uid associated with the archive member, encoded as a +decimal number. +.It Ar ar_gid +(6 bytes) The gid associated with the archive member, encoded as a +decimal number. +.It Ar ar_mode +(8 bytes) The file mode for the archive member, encoded as an octal +number. +.It Ar ar_size +(10 bytes) In the SVR4/GNU archive format this field holds the size in +bytes of the archive member, encoded as a decimal number. +In the BSD archive format, for short file names, this field +holds the size in bytes of the archive member, encoded as a decimal +number. +For long file names +.Po +see +.Sx "Representing File Names" +below +.Pc , +the field contains the combined size of the +archive member and its file name, encoded as a decimal number. +.It Ar ar_fmag +(2 bytes) This field holds 2 bytes with values 0x96 and 0x0A +respectively, marking the end of the header. +.El +.Pp +Unused bytes in the fields of an archive header are set to the value +0x20. +.Ss "Representing File Names" +The BSD and SVR4/GNU variants use different schemes for encoding file +names for members. +.Bl -tag -width "SVR4/GNU" +.It "BSD" +File names that are upto 16 bytes long and which do not contain +embedded spaces are stored directly in the +.Ar ar_name +field of the archive header. +File names that are either longer than 16 bytes or which contain +embedded spaces are stored immediately after the archive header +and the +.Ar ar_name +field of the archive header is set to the string +.Dq "#1/" +followed by a decimal representation of the number of bytes needed for +the file name. +In addition, the +.Ar ar_size +field of the archive header is set to the decimal representation of +the combined sizes of the archive member and the file name. +The file contents of the member follows the file name without further +padding. +.Pp +As an example, if the file name for a member was +.Dq "A B" +and its contents was the string +.Dq "C D" , +then the +.Ar ar_name +field of the header would contain +.Dq Li "#1/3" , +the +.Ar ar_size +field of the header would contain +.Dq Li 6 , +and the bytes immediately following the header would be 0x41, 0x20, +0x42, 0x43, 0x20 and 0x44 +.Po +ASCII +.Dq "A BC D" +.Pc . +.It "SVR4/GNU" +File names that are upto 15 characters long are stored directly in the +.Ar ar_name +field of the header, terminated by a +.Dq Li / +character. +.Pp +If the file name is larger than would fit in space for the +.Ar ar_name +field, then the actual file name is kept in the archive +string table +.Po +see +.Sx "Archive String Tables" +below +.Pc , +and the decimal offset of the file name in the string table is stored +in the +.Ar ar_name +field, prefixed by a +.Dq Li / +character. +.Pp +As an example, if the real file name has been stored at offset 768 in +the archive string table, the +.Ar ar_name +field of the header will contain the string +.Dq /768 . .El -.It Va ar_size -In the SVR4/GNU variant, this field holds the decimal representation -of actual size in bytes of the archived file. -In the BSD variant, for member names that use the -.Va ar_name -field directly, this field holds the decimal representation of the -actual size in bytes of the archived member. -For member names that use the extension mechanism described above, the -field will hold the sum of the sizes, in bytes, of the filename and the -archive member. -.It Va ar_uid -This field holds the decimal representation of the numeric -group id of the creator of the member. +.Ss "Special Archive Members" +The following archive members are special. +.Bl -tag -width indent +.It Dq Li / +In the SVR4/GNU variant of the archive format, the archive member with +name +.Dq Li / +denotes an archive symbol table. +If present, this member will be the very first member in the +archive. +.It Dq Li // +In the SVR4/GNU variant of the archive format, the archive member with +name +.Dq Li // +denotes the archive string table. +This special member is used to hold filenames that do not fit in the +file name field of the header +.Po +see +.Sx "Representing File Names" +above +.Pc . +If present, this member immediately follows the archive symbol table +if an archive symbol table is present, or is the first member otherwise. +.It Dq Li "__.SYMDEF" +This special member contains the archive symbol table in the BSD +variant of the archive format. +If present, this member will be the very first member in the +archive. .El -.Ss Archive Symbol Table -An archive may additionally contain an archive symbol table -used by the link editor, -.Xr ld 1 . -This symbol table has the member name -.Qq __.SYMDEF -in the BSD variant of the archive format, and the name -.Qq / -in the SVR4/GNU variant. +.Ss "Archive String Tables" +An archive string table is used in the SVR4/GNU archive format to hold +file names that are too large to fit into the constraints of the +.Ar ar_name +field of the archive header. +An archive string table contains a sequence of file names. +Each file name in the archive string table is terminated by the +byte sequence 0x2F, 0x0A +.Po +the ASCII string +.Dq "/\en" +.Pc . +No padding is used to separate adjacent file names. +.Ss "Archive Symbol Tables" +Archive symbol tables are used to speed up link editing by providing a +mapping between the program symbols defined in the archive +and the corresponding archive members. +Archive symbol tables are managed by the +.Xr ranlib 1 +utility. .Pp -The format of the symbol table depends on the format variant: -.Bl -tag -width "SVR4/GNU" -compact +The format of archive symbol tables is as follows: +.Bl -tag -width "SVR4/GNU" .It BSD -In the BSD variant, the symbol table has 4 parts encoded in -a machine dependent manner: -.Bl -enum -compact -.It -The first part is a binary value containing size in bytes of the -second part encoded as a C -.Dq long . -.It -The second part is a list of -.Vt struct ranlib -structures (see -.In ranlib.h Ns ). -Each ranlib structure describes one symbol and comprises of -two C -.Dq long -values. -The first -.Dq long -is a zero-based offset into the string table in the fourth part -for the symbol's name. -The second -.Dq long -is an offset from the beginning of the archive to the start -of the archive header for the member that defines the symbol. -.It -The third part is a binary value denoting the length of the -string table contained in the fourth part. -.It -The fourth part is a string table containing NUL-terminated -strings. +In the BSD archive format, the archive symbol table comprises +of two parts: a part containing an array of +.Vt "struct ranlib" +descriptors, followed by a part containing a symbol string table. +The sizes and layout of the structures that make up a BSD format +archive symbol table are machine dependent. +.Pp +The part containing +.Vt "struct ranlib" +descriptors begins with a field containing the size in bytes of the +array of +.Vt "struct ranlib" +descriptors encoded as a C +.Vt long +value. +.Pp +The array of +.Vt "struct ranlib" +descriptors follows the size field. +Each +.Vt "struct ranlib" +descriptor describes one symbol.
