(3) (C++11 feature)

1) Compares two sub_match directly by comparing their underlying character sequences. This function is implemented as follows.

2) Compares a sub_match with a std::basic_string. This function is implemented as follows.

3) Compares a sub_match with a C-style NULL-terminated sequence of teh underlying character type. This function is implemented as follows.

This function is infrequently used directly by application code. Instead, one of the non-member comparison operators are used.

[edit] Parameters

m - A pointer to another sub_match.
s - A pointer to a std::basic_string to compare.
c - A pointer to a C-style null-terminated character sequence of the underlying value_type to compare.

[edit] Return value

A value less than zero if this sub_match is less than the other character sequence, zero if the both underlyinging character sequences are equal, greater than zero if this sub_match is greater than the other character sequence.
