NAME
wcsdup - save a copy of a wide string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <wchar.h>
wchar_t *
wcsdup(const wchar_t *str);
DESCRIPTION
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.
EXAMPLES
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);
}
ERRORS
The wcsdup() function may fail and set the external variable errno for
any of the errors specified for the library function malloc(3).
SEE ALSO
free(3), malloc(3), strdup(3)
