Here is my project in detail. - I have a PID (from getpid) - Then I want to look what program has that PID (by looking at the /proc/pid/map) - next I must know what libraries are utilized, and their text segments (where the code are allocated) So looking at the /proc/pid/map (just the text segments, identified by 'r-x' mode): In FreeBSD: 0x8048000 0x8049000 1 0 0xc8776d20 r-x 2 0 0x0 COW NC vnode 0x28049000 0x2805a000 12 0 0xc03f9f80 r-x 73 34 0x0 COW NC vnode 0x28065000 0x280e5000 57 0 0xc03fad60 r-x 73 34 0x0 COW NC vnode In Linux: 8048000-08049000 r-xp 00000000 03:08 22408 /rdata/src/test/loop/a.out 40000000-40016000 r-xp 00000000 03:08 44178 /lib/ld-2.1.92.so 40022000-4013d000 r-xp 00000000 03:08 44185 /lib/libc-2.1.92.so I know the first one is the executable itself, the 2nd one should be the dynamic linker, and the third one is the C library. The first and 2nd column are the starting and ending text/code segment. Now the problem is: I don't know what is the executable name, and the libraries utilized from /proc/pid/map in FreeBSD. In Linux I can easily get them from the last column. Where can I get those names in FreeBSD? I assume the numbers in the third column (1, 12, 57) mean something, but I don't know what they are.
