Determines the length in bytes of a multibyte character.
Standard C Library (libc.a)
#include <stdlib.h>
int mblen( MbString, Number)
const char *MbString;
size_t Number;
The mblen subroutine determines the length, in bytes, of a multibyte character.
| Mbstring | Points to a multibyte character string. |
| Number | Specifies the maximum number of bytes to consider. |
The mblen subroutine returns 0 if the MbString parameter points to a null character. It returns -1 if a character cannot be formed from the number of bytes specified by the Number parameter. If MbString is a null pointer, 0 is returned.
