static VALUE
rb_str_match_m_p(int argc, VALUE *argv, VALUE str)
{
VALUE re;
rb_check_arity(argc, 1, 2);

return rb_reg_match_p(re, str, argc > 1 ? NUM2LONG(argv[1]) : 0);
}
Returns whether a match is found for self and the given arguments; does not update Regexp Global Variables.
Computes regexp by converting pattern (if not already a Regexp):
Example
regexp = Regexp.new(pattern)
Returns true if self[offset..].match(regexp) returns a MatchData object, false otherwise:
Example
'foo'.match?(/o/) # => true 'foo'.match?('o') # => true 'foo'.match?(/x/) # => false 'foo'.match?('f', 1) # => false 'foo'.match?('o', 1) # => true
