NAME
wcslen - get wide-character string length
SYNOPSIS
#include <wchar.h>
size_t wcslen(const wchar_t *ws);
DESCRIPTION
The wcslen() function shall compute the number of wide-character codes in the wide-character string to which ws points, not including the
terminating null wide-character code.
RETURN VALUE
The wcslen() function shall return the length of ws; no return value is reserved to indicate an error.
ERRORS
No errors are defined.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
None.

Hi,
wcslen(), strlen() returns size_t.
On 64-bit platform i want to use int like
str length is 10.
int len = wcslen(str);
On 64-bit what should I need to do if i wants the length in int. Because getting error as "Conversion of 64 bit type value to "int" causes truncation".
if i... (17 Replies)
