WCSDUP(3) Library Functions Manual WCSDUP(3)

wcsdup
save a copy of a wide string

Standard C Library (libc, -lc)

#include <wchar.h>

wchar_t *
wcsdup(const wchar_t *str);

The wcsdup() function allocates sufficient memory for a copy of the wide-character string str, does the copy, and returns a pointer to it. The pointer may subsequently be used as an argument to the function free(3).

If insufficient memory is available, NULL is returned.

The following will point p to an allocated area of memory containing the nul-terminated string “foobar”:
wchar_t *p;

if (p = wcsdup(L"foobar"), p == NULL) {
	fprintf(stderr, "Out of memory.\n");
	exit(1);
}

The wcsdup() function may fail and set the external variable errno for any of the errors specified for the library function malloc(3).

free(3), malloc(3), strdup(3)

The wcsdup() function first appeared in NetBSD 4.0.
