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).
HISTORY
The wcsdup() function first appeared in NetBSD 4.0.
