/* Simple front end to regular expressions.
|
|
|
|
This is a simple front end to make the usage of regular expressions
|
|
easier. The routine tests whether the pattern provided in 'pattern'
|
|
matches the text in 'buffer' or not. Comparisons are done
|
|
case-insensitive, using the extended regular expression language.
|
|
|
|
RETURNS: If the pattern matches, TRUE is returned. Otherwise the
|
|
routine will return FALSE.
|
|
|
|
NOTE: The error handling is somewhat relaxed... well, don't use the
|
|
routine if you need error handling.
