The shexp_casecmp function validates a specified shell expression and compares it with a specified string. The function returns one of three possible values representing match, no match, and invalid comparison. This comparison, in contrast to that of the shexp_cmp function, is not 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_casecmp(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.
