I don't remember if I included the following in my PR: .\" @(#)string.3 1.33 90/02/15 SMI; from UCB 4.2 and S5 The reference to S5 I think ought to account for differences. In case anyone is curious, I include the man page off the TAHOE UNIX tape for reference. This is from a 9-track marked "4.3BSD-tahoe TAHOE UNIX System 7/25/88"---sorry but I can't help much with the SysV.. I powered up an old UNIX PC we have running "UNIX SYSTEM5 3.51m," but it did not have a strdup declared in string.h. Mika >Hmm... Here's another one...

They do not check for overflow of any receiving string. .PP \fIStrcat\fP appends a copy of string \fIappend\fP to the end of string \fIs\fP. \fIStrncat\fP copies at most \fIcount\fP characters. Both return a pointer to the null-terminated result. .PP \fIStrcmp\fP compares its arguments and returns an integer greater than, equal to, or less than 0, according as \fIs1\fP is lexicographically greater than, equal to, or less than \fIs2\fP. \fIStrncmp\fP makes the same comparison but looks at at most \fIcount\fP characters. \fIStrcasecmp\fP and \fIstrncasecmp\fP are identical in function, but are case insensitive. The returned lexicographic difference reflects a conversion to lower-case. .PP \fIStrcpy\fP copies string \fIfrom\fP to \fIto\fP, stopping after the null character has been moved. \fIStrncpy\fP copies exactly \fIcount\fP characters, appending nulls if \fIfrom\fP is less than \fIcount\fP characters in length; the target may not be null-terminated if the length of \fIfrom\fP is \fIcount\fP or more. Both return \fIto\fP. .PP \fIStrlen\fP returns the number of non-null characters in \fIs\fP. .PP .I Index .RI ( rindex ) returns a pointer to the first (last) occurrence of character \fIc\fP in string \fIs\fP or zero if \fIc\fP does not occur in the string. Setting \fIc\fP to NULL works. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
