NAME
patmatch() - checks string for matchesSYNOPSIS
char *patmatch(pattern, aux, string, soff, slen, alt, state) char *pattern; int *aux; char *string; int soff; int slen; int alt; int state[];
DESCRIPTION
patmatch() uses the pattern matching information pattern and in addition aux and alt (previously set up by a call to patcompile(3)) to check string for a match. The length of the string is slen and the starting index used for matching is soff. The string can also be terminated by a null byte.The state array is set up and used internally by patmatch and should have at least strlen(pattern) + 1 elements.
RETURNS
Returns a NULL pointer if the string starting at the specified offset did not match the pattern.Any non-NULL return is a pointer to the first character of string after the part that matches.
SEE ALSO
patcompile(3) for information on aux and alt.And match(1) for a description ot the regular expressions.
NOTES
The pattern matching functions are based on ones presented by Martin Richards in "A Compact Function for Regular Expression Pattern Matching", Software-Practice and Experience vol 9, 527-534 (1979).| 12. Nov 2000 | Joerg Schilling |
