Template:cpp/string/multibyte/sidebar
| Defined in header <cstdlib>

| int mblen( const char* s, std::size_t n ); |

Determines the size, in bytes, of the multibyte character whose first byte is pointed to by s
If s is a null pointer, determines if the current locale's multibyte character encoding is state-dependent.
This function is equivalent to the call Template:cpp, except that conversion state of Template:cpp is unaffected.

Parameters
| s | - | pointer to the multibyte character |
| n | - | limit on the number of bytes in s that can be examined |
Return value
If s is not a null pointer, returns the number of bytes that are contained in the multibyte character or Template:cpp if the first bytes pointed to by s do not form a valid multibyte character or Template:cpp if s is pointing at the null charcter Template:cpp.
If s is a null pointer, returns Template:cpp if multibyte encoding is not state-dependent or a non-zero value if multibyte encoding is state-dependent.
