15 wcsdup():
16 Since glibc 2.10:
17 _POSIX_C_SOURCE >= 200809L
18 Before glibc 2.10:
19 _GNU_SOURCE

22 The wcsdup() function is the wide-character equivalent of the strdup(3)
23 function. It allocates and returns a new wide-character string whose
24 initial contents is a duplicate of the wide-character string pointed to
25 by s.
26
27 Memory for the new wide-character string is obtained with malloc(3),
28 and should be freed with free(3).
29
31 On success, wcsdup() returns a pointer to the new wide-character
32 string. On error, it returns NULL, with errno set to indicate the
33 cause of the error.
34
36 ENOMEM Insufficient memory available to allocate duplicate string.
