The C standard says (C23 K.3.6.2.1):
The getenv_s function returns zero if the specified name is found and the
associated string was successfully stored in value . Otherwise, a nonzero value
is returned
However getenv_s in the UCRT reports success (return value is 0) for
non-exisiting environment variables:
#include <windows.h>
#include <stdlib.h>
#include <assert.h>
int
main (void)
{
char value[100];
size_t len;
errno_t ret;
ret = getenv_s (&len, value, sizeof (value), "NONEXISTING");
assert (ret != 0);
}
Should we provide a wrapper?
Best Regards,
Luca
