int compare( const sub_match& m ) const; | (1) | (since C++11) |

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.
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 |
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.
