NAME
wctomb - convert a wide-character code to a character SYNOPSIS
#include <stdlib.h> int wctomb(char *s, wchar_t wchar); DESCRIPTION
The wctomb() function determines the number of bytes needed to represent the character corresponding to the wide-character code whose value is wchar. It stores the character representation (possibly multiple bytes) in the array object pointed to by s (if s is not a null pointer). At most MB_CUR_MAX bytes are stored. A call with s as a null pointer causes this function to return 0. The behavior of this function is affected by the LC_CTYPE category of the current locale. RETURN VALUES
If s is a null pointer, wctomb() returns 0 value. If s is not a null pointer, wctomb() returns -1 if the value of wchar does not correspond to a valid character, or returns the number of bytes that constitute the character corresponding to the value of wchar. In no case will the value returned be greater than the value of the MB_CUR_MAX macro. ERRORS
No errors are defined. USAGE
The wctomb() function can be used safely in a multithreaded application, as long as setlocale(3C) is not being called to change the locale. ATTRIBUTES

NAME
mbtowc - convert a character to a wide-character code SYNOPSIS
#include <stdlib.h> int mbtowc(wchar_t *restrict pwc, const char *restrict s, size_t n); DESCRIPTION
If s is not a null pointer, mbtowc() determines the number of the bytes that constitute the character pointed to by s. It then determines the wide-character code for the value of type wchar_t that corresponds to that character. (The value of the wide-character code correspond- ing to the null byte is 0.) If the character is valid and pwc is not a null pointer, mbtowc() stores the wide-character code in the object pointed to by pwc. A call with s as a null pointer causes this function to return 0. The behavior of this function is affected by the LC_CTYPE category of the current locale. At most n bytes of the array pointed to by s will be examined. RETURN VALUES
If s is a null pointer, mbtowc() returns 0. If s is not a null pointer, mbtowc() returns 0 (if s points to the null byte), the number of bytes that constitute the converted character (if the next n or fewer bytes form a valid character), or -1 and may set errno to indicate the error (if they do not form a valid character). In no case will the value returned be greater than n or the value of the MB_CUR_MAX macro. ERRORS
The mbtowc() function may fail if: EILSEQ Invalid character sequence is detected. USAGE
The mbtowc() function can be used safely in multithreaded applications, as long as setlocale(3C) is not being called to change the locale. ATTRIBUTES
