1) Compares two sub_match directly by comparing their underlying character sequences. Equivalent to str().compare(m.str())
2) Compares a sub_match with a std::basic_string. This function is implemented as follows. Equivalent to str().compare(s)
3) Compares a sub_match with a null-terminated sequence of the underlying character type pointed to by
s. Equivalent to str().compare(c)
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 string to compare to |
| c | - | a pointer to a null-terminated character sequence of the underlying value_type to compare to |
[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.
