NAME¶

std::sub_match::compare - std::sub_match::compare

Synopsis¶

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)

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. 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 is used.

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 than the other character sequence.
