wcstombs(3int)wcstombs(3int)Namewcstombs - converts a string of type wchar_t into a multibyte character
string
Syntax
#include <stdlib.h>
int wcstombs (s, pwcs, n)
char *s;
const wchar_t *pwcs;
size_t n;
Arguments
s The s argument is a pointer to the resulting multibyte charac‐
ter string.
pwcs The pwcs argument is a pointer to the source array of wide
characters.
n The n argument is the maximum number of resulting bytes in the
array pointed to by s.
Description
The function converts a sequence of character codes of type from the
array pointed to by pwcs into a sequence of multibyte characters. The
function stores the multibyte characters in the array pointed to by s,
stopping if a multibyte character would exceed the limit of n total
bytes or if a null character is stored. Each character is converted as
if by a call to the function. No more than n bytes are modified in the
array pointed to by s. This function is affected by the LC_CTYPE cate‐
gory of the current locale.
Return Values
If a character is encountered that does not correspond to a valid
multi-byte character, the function returns Otherwise, the function
returns the number of bytes modified, not including a terminating null
character, if any. The array will not be null-terminated if the value
returned is n.
