The shexp_casecmp function validates a specified shell expression and compares it with a specified string. It returns one of three possible values representing match, no match, and invalid comparison. The comparison (in contrast to that of the shexp_casecmp function) is case-sensitive.
Use this function if you have a shell expression like *.netscape.com and you want to make sure that a string matches it, such as foo.netscape.com.
int shexp_cmp(char *str, char *exp);
0 if a match was found.
1 if no match was found.
-1 if the comparison resulted in an invalid expression.
char *str is the string to be compared.
char *exp is the shell expression (wildcard pattern) to compare against.
/* Use wildcard match to see if this path is one we want */char *path;char *match = "/usr/netscape/*";if (shexp_cmp(path, match) != 0) return REQ_NOACTION; /* no match */
