Defined in header <stdlib.h>
int wctomb( char* s, wchar_t wc );
Converts a wide character
wc to multibyte encoding and stores it (including any shift sequences) in the char array whose first element is pointed to by
s. No more than MB_CUR_MAX characters are stored.
wc is the null character, the null byte is written to
s, preceded by any shift sequences necessary to restore the initial shift state.
s is a null pointer, resets the global conversion state and determines whether shift sequences are used.
Each call to
wctomb updates the internal global conversion state (a static object of type mbstate_t, only known to this function). If the multibyte encoding uses shift states, this function is not reentrant. In any case, multiple threads should not call
wctomb without synchronization: wcrtomb may be used instead.
|s||-||pointer to the character array for output|
|wc||-||wide character to convert|
 Return value
s is not a null pointer, returns the number of bytes that are contained in the multibyte representation of
wc or -1 if
wc is not a valid character.
s is a null pointer, resets its internal conversion state to represent the initial shift state and returns 0 if the current multibyte encoding is not state-dependent (does not use shift sequences) or a non-zero value if the current multibyte encoding is state-dependent (uses shift sequences).
