wcsdup - duplicate a wide-character string
#include <wchar.h>
wchar_t *wcsdup(const wchar_t *s);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
wcsdup():
Since glibc 2.10:
_POSIX_C_SOURCE >= 200809L
Before glibc 2.10:
_GNU_SOURCE
The wcsdup() function is the wide-character equivalent of the
strdup(3) function. It allocates and returns a new wide-character
string whose initial contents is a duplicate of the wide-character
string pointed to by s.
Memory for the new wide-character string is obtained with malloc(3),
and should be freed with free(3).
On success, wcsdup() returns a pointer to the new wide-character
string. On error, it returns NULL, with errno set to indicate the
cause of the error.
ENOMEM Insufficient memory available to allocate duplicate string.
For an explanation of the terms used in this section, see
attributes(7).
