mbsinit - C wchar.h

Type

function

From


<cwchar>
<wchar.h>

Prototype

int mbsinit (const mbstate_t* ps);

Description

Checks whether ps points to a mbstate_t object that describes an initial conversion state.

The state pointed by ps can be set to the initial state by calling:

memset (ps,0,sizeof(*ps));  // ps points now to a zero-valued object

Parameters

Parameter	Description
ps	Pointer to an mbstate_t object.

Return Value

A non-zero value if ps can describe an initial conversion state, or if ps is a null pointer.

Otherwise, a zero value is returned.
