Compares a sub_match to another sub_match, a string, a null-terminated character sequence or a character.

1-6) Compares two sub_match directly by comparing their underlying character sequences. Implemented using lhs.str().compare(rhs.str())

7-18) Compares a sub_match with a std::basic_string. Implemented using sm.str().compare(st), where sm is a sub_match and st is a basic_string.

19-30) Compares a sub_match with a null-terminated string. Implemented using sm.str().compare(s), where sm is a sub_match and s is a pointer to a null-terminated character string.

31-42) Compares a sub_match with a character. Implemented using the following:

sm.str().compare(typename sub_match<BidirIt>::string_type(1, ch)), where sm is a sub_match and ch is a character.

Parameters

lhs, rhs

-

a sub_match, basic_string, pointer to a null-terminated string or a character to compare

Return value

true if the corresponding comparison holds as defined by compare(), false otherwise.
