std::sub_match::compare (3) Linux Manual Page
std::sub_match<BidirIt>::compare – std::sub_match<BidirIt>::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 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.
