The manual page for strdup(3) claims:
HISTORY
The strdup() function first appeared in 4.4BSD.
BSD June 9, 1993 1
This is wrong. strdup() is documented in SunOS 4.1.1 (and earlier),
at least as early as 1987.
From SunOS 4.1.1/sun3:
.\" @(#)string.3 1.33 90/02/15 SMI; from UCB 4.2 and S5
.TH STRING 3 "6 October 1987"
.SH NAME
strcat, strncat, strdup, strcmp, strncmp, strcasecmp, strncasecmp, strcpy, strnc
py, strlen, strchr, strrchr, strpbrk, strspn, strcspn, strstr, strtok, index, ri
ndex \- string operations
It is not present in Tahoe UNIX though (dated 22 Oct 1987, two weeks after
the SMI man page), so I assume it is actually from AT&T System V.
The only reason I bring this up is that the manual page might lead a
programmer to believe (such as I did in shock after having used strdup
with abandon for several years) that use of strdup will lead to
less portable programs than it actually does.
>How-To-Repeat:
freebsd% man 3 strdup
>Fix:
Edit the man page to say .. don't know.. "Probably from System V"?
