std::char_traits::to_int_type(3) | C++ Standard Libary | std::char_traits::to_int_type(3) |
NAME¶
std::char_traits::to_int_type - std::char_traits::to_int_type
Synopsis¶
static int_type to_int_type( char_type c ); (until C++11)
static constexpr int_type to_int_type( char_type c ) noexcept; (since
C++11)
Converts a value of char_type to int_type.
Parameters¶
c - value to convert
Return value¶
A value equivalent to c.
Complexity¶
Constant.
Notes¶
For every valid value of char_type, there must be a unique value
of int_type
distinct from eof(). For example, a common implementation of
char_traits<char>::eof() is return -1, and a corresponding valid
implementation of
char_traits<char>::to_int_type(c) is return (unsigned char)c.
