Common <options> are REG_ICASE and REG_NEWLINE. For other possible option flags,
|
|
see regex(3) man page. You don't need to specify REG_EXTENDED.
|
|
|
|
<nmatch> is the number of subexpressions to match.
|
|
Returns an array of strings. The first string is the matching substring,
|
|
the remaining are the matching subexpressions, up to nmatch+1 number.
|
|
|
|
If nmatch is -1, works like grep. Returns an array containing self if matching.
|
|
|
|
Returns nil if regular expression does not match or if an error has occurred.
