std::sub_match<BidirIt>::compare
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; |

1) Compares two sub_match 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).This function is infrequently used directly by application code. Instead, one of the non-member comparison operators are 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.
