1) Compares two
sub_matches directly by comparing their underlying character sequences. Equivalent to
str(
).compare
(m.str
(
)
)
3) Compares a
sub_match with a null-terminated sequence of the underlying character type pointed to by s. Equivalent to str().compare(c)
Parameters
| m | - | a reference to another sub_match |
| s | - | a reference to a string to compare to |
| c | - | a pointer to a null-terminated character sequence of the underlying value_type to compare to
|
Return value
A value less than zero if this sub_match is less than the other character sequence, zero if the both underlying character sequences are equal, greater than zero if this sub_match is greater
Notes
This function is infrequently used directly by application code. Instead, one of the non-member comparison operators is used.
