NAME
 pmatch — performs pattern matching on strings
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.
