NAME



wcsrtombs

 
wcsnrtombs

 - convert a wide-character string to a character string (restartable)

LIBRARY

Lb libc

SYNOPSIS

#include <wchar.h>
size_t Fo wcsrtombs Fa char * restrict dst const wchar_t ** restrict src Fa size_t len mbstate_t * restrict ps Fc Ft size_t Fo wcsnrtombs Fa char * restrict dst const wchar_t ** restrict src size_t nwc Fa size_t len mbstate_t * restrict ps Fc

DESCRIPTION

The wcsrtombs ();
function converts a string of wide characters indirectly pointed to by Fa src to a corresponding multibyte character string stored in the array pointed to by Fa dst . No more than Fa len bytes are written to Fa dst .

If Fa dst is NULL no characters are stored.

If Fa dst is not NULL the pointer pointed to by Fa src is updated to point to the character after the one that conversion stopped at. If conversion stops because a null character is encountered, Fa *src is set to NULL

The Vt mbstate_t argument, Fa ps , is used to keep track of the shift state. If it is NULL wcsrtombs ();
uses an internal, static Vt mbstate_t object, which is initialized to the initial conversion state at program startup.

The wcsnrtombs ();
function behaves identically to wcsrtombs (,);
except that conversion stops after reading at most Fa nwc characters from the buffer pointed to by Fa src .

RETURN VALUES

The wcsrtombs ();
and wcsnrtombs ();
functions return the number of bytes stored in the array pointed to by Fa dst (not including any terminating null), if successful, otherwise it returns Po Vt size_t Pc Ns -1 .
