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 -1, with errno set to indicate
the cause of the error.
- ENOMEM
- Insufficient memory available to allocate
duplicate string.
POSIX.1-2008. This function is not specified
in POSIX.1-2001, and is not widely available on other systems.
