The
wcsdup function is the wide-character equivalent of the
strdup
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
can be freed with
free(3).
The
wcsdup function returns a pointer to the new wide-character string,
or NULL if sufficient memory was not available.
- ENOMEM
- Insufficient memory available to allocate duplicate
string.
This function is a GNU extension.
