NAME

pmatch — performs pattern matching on strings

#include <sys/systm.h>

int
pmatch(const char *string, const char *pattern, const char **estr);

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.

pmatch() will return 2 for an exact match, 1 for a substring match, 0 for no match and -1 if an error occurs.
