right, what I meant was I was hoping I could use something like strncmp() instead that would know how to treat NULL...etc..

thanks again though, I think your latter suggestion is the way I'll have to go.

If this is the case, then the GDB... (2 Replies)

STRCMP(3)						   BSD Library Functions Manual 						 STRCMP(3)

NAME
strcmp, strncmp -- compare strings LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <string.h> int strcmp(const char *s1, const char *s2); int strncmp(const char *s1, const char *s2, size_t len); DESCRIPTION
The strcmp() and strncmp() functions lexicographically compare the nul-terminated strings s1 and s2. RETURN VALUES
The strcmp() and strncmp() return an integer greater than, equal to, or less than 0, according to whether the string s1 is greater than, equal to, or less than the string s2. The comparison is done using unsigned characters, so that '200' is greater than ''. The strncmp() compares not more than len characters. SEE ALSO
bcmp(3), memcmp(3), strcasecmp(3), strcoll(3), strxfrm(3) STANDARDS
The strcmp() and strncmp() functions conform to ANSI X3.159-1989 (``ANSI C89''). NOTES
If len is zero strncmp() returns always 0. BSD
