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 as if by lhs.compare(rhs)
7-18) Compares a sub_match with a std::basic_string. Implemented as if by sm.compare(typename sub_match<BidirIt>::string_type(st.data(), st.size()), where sm is the sub_match argument and st is the basic_string argument.
19-30) Compares a sub_match with a null-terminated string. Implemented as if by sm.compare(s), where sm is the sub_match and s is the pointer to a null-terminated character string.
31-42) Compares a sub_match with a character. Implemented as if by sm.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 std::sub_match::compare(), false otherwise.
