Convert a wide-character code to a character
#include <wchar.h> size_t wcrtomb( char * s, wchar_t wc, mbstate_t * ps);
- NULL, or a pointer to a location where the function can store the multibyte character.
- The wide character that you want to convert.
- An internal pointer that lets wcrtomb() be a restartable
if ps is NULL, wcrtomb() uses its
own internal variable.
You can call mbsinit() to determine the status of this variable.
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The wcrtomb() function determines the number of bytes needed to represent the wide character wc as a multibyte character and stores the multibyte character in the location pointed to by s, to a maximum of MB_CUR_MAX bytes.
This function is affected by LC_CTYPE.
The number of bytes stored, or (size_t)-1 if the variable wc is an invalid wide-character code.
- Invalid wide-character code.
- The variable ps points to an invalid conversion state.
