shexp_match

The shexp_match function compares a specified prevalidated shell expression against 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.

The shexp_match function doesn’t perform validation of the shell expression; instead the function assumes that you have already called shexp_valid.

Use this function if you have a shell expression such as *.netscape.com, and you want to make sure that a string matches it, such as foo.netscape.com.

Syntax

int shexp_match(char *str, char *exp);

Returns

0 if a match was found.

1 if no match was found.

-1 if the comparison resulted in an invalid expression.

Parameters

char *str is the string to be compared.

char *exp is the prevalidated shell expression (wildcard pattern) to compare against.
