SYNOPSIS
#include <sys/systm.h>
int
pmatch(const char *string, const char *pattern, const char **estr);
DESCRIPTION
Extract substring matching pattern from string. If not NULL, estr points to the end of the longest exact or substring match.
 
pmatch() uses the following metacharacters:
?
match any single character.
*
match any character 0 or more times.
[
define a range of characters that will match. The range is defined by 2 characters separated by a ‘-'. The range definition has to end with a ‘]'. A ‘^' following the ‘[' will negate the range.
RETURN VALUES
pmatch() will return 2 for an exact match, 1 for a substring match, 0 for no match and -1 if an error occurs.
