NAME
wctomb - convert a wide character to a multibyte sequence
SYNOPSIS
#include <stdlib.h> int wctomb(char *s, wchar_t wc);
DESCRIPTION
If s is not NULL, the wctomb function converts the wide character wc to its multibyte representation and stores it at the beginning of the character array pointed to by s. It updates the shift state, which is stored in a static anonymous variable only known to the wctomb func- tion, and returns the length of said multibyte representation, i.e. the number of bytes written at s. The programmer must ensure that there is room for at least MB_CUR_MAX bytes at s. If s is NULL, the wctomb function resets the shift state, only known to this function, to the initial state, and returns non-zero if the encoding has non-trivial shift state, or zero if the encoding is stateless.
RETURN VALUE
If s is not NULL, the wctomb function returns the number of bytes that have been written to the byte array at s. If wc can not be repre- sented as a multibyte sequence (according to the current locale), -1 is returned. If s is NULL, the wctomb function returns non-zero if the encoding has non-trivial shift state, or zero if the encoding is stateless.

NOTES
The behaviour of wctomb depends on the LC_CTYPE category of the current locale. This function is not multi-thread safe. The function wcrtomb provides a better interface to the same functionality.
