C library function int mbtowc(whcar_t *pwc, const char *str, size_t n)Convert a multi-byte sequence to wide characters.
The following is the declaration of the mbtowc() function.
int mbtowc(whcar_t *pwc, const char *str, size_t n)
The parameters are as follows:
pwc − This is a pointer to a wchar_t type object.
#str − This is a pointer to the first byte of a multibyte character.
#str − This is a pointer to the first byte of a multibyte character.
#n − This is the maximum number of bytes to check for character length.
The return value is as follows:
If str is not NULL, the mbtowc() function returns the number of bytes consumed starting from str. If Returns 0 if s points to a null byte, or -1 on failure.
If str is NULL, the mbtowc() function returns a non-zero value, indicating that the encoding has a non-trivial shift state, or zero if the encoding is stateless.
