Overview
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).
Return value
On success, wcsdup() returns a pointer to the new wide-character string. On error, it returns NULL, with errno set to indicate the error.
Errors
- ENOMEM
-
Insufficient memory available to allocate duplicate string.
