read file line by line and use strtok(), if user names are seperated by space. and then use strcmp() with each token to compare user names.

STRSEP(3)						     Linux Programmer's Manual							 STRSEP(3)

NAME
strsep - extract token from string SYNOPSIS
#include <string.h> char *strsep(char **stringp, const char *delim); DESCRIPTION
If *stringp is NULL, the strsep() function returns NULL and does nothing else. Otherwise, this function finds the first token in the string *stringp, where tokens are delimited by symbols in the string delim. This token is terminated with a `' character (by overwriting the delimiter) and *stringp is updated to point past the token. In case no delimiter was found, the token is taken to be the entire string *stringp, and *stringp is made NULL. RETURN VALUE
The strsep() function returns a pointer to the token, that is, it returns the original value of *stringp. NOTES
The strsep() function was introduced as a replacement for strtok(), since the latter cannot handle empty fields. However, strtok() con- forms to ANSI-C and hence is more portable. BUGS
This function suffers from the same problems as strtok(). In particular, it modifies the original string. Avoid it. CONFORMING TO
