mbtowc

Translate a multibyte character to a wchar_t type.

Compatibility:

This function is compatible with the following targets:

ANSI

BeOS

EMB/RTOS

Mac OS

Palm OS

Win32


Prototype:
#include <stdlib.h>
int mbtowc(wchar_t *pwc,
   const char *s, size_t n);
Parameters:

Parameters for this facility are:

pwc  
wchar_t *  
The wide character destination  
s  
const char *s  
The string to convert  
n  
size_t  
The maximum wide characters to convert  

Remarks:

The mbtowc() function converts a multibyte character, pointed to by s, to a character of type wchar_t, pointed to by pwc. The function converts a maximum of n bytes.

The Metrowerks C implementation performs no translation; it copies the first character at s to the first character at pwc.

Return:

mbtowc() returns -1 if n is zero and s is not a null pointer.

mbtowc() returns 0 if s is a null pointer or s points to a null character ('\0').

mbtowc() returns 1 if s is not a null pointer and it does not point to a null character ('\0').
