DESCRIPTION¶

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 -1, with errno set to indicate the cause of the error.

ERRORS¶

ENOMEM

Insufficient memory available to allocate duplicate string.
