std::sub_match::compare - cppreference.com (original) (raw)
| int compare( const sub_match& m ) const; | (1) | (since C++11) |
|---|---|---|
| int compare( const string_type& s ) const; | (2) | (since C++11) |
| int compare( const value_type* c ) const; | (3) | (since C++11) |
Compares two
sub_matches directly by comparing their underlying character sequences. Equivalent to str().compare(m.str()).Compares a
sub_matchwith a std::basic_string. Equivalent to str().compare(s).Compares a
sub_matchwith a null-terminated sequence of the underlying character type pointed to by s. Equivalent to str().compare(c).
[edit] 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 |
[edit] 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 than the other character sequence.
[edit] Notes
This function is infrequently used directly by application code. Instead, one of the non-member comparison operators is used.
