why could I not write static time_t current_time = time(); in c program?

Hi,

i write
static time_t current_time = time();

but the gcc compiler complains:
error: initializer element is not constant.

I want to know
1, why,
2, and how to resovle it.

thanks.

Hi,

i write
static time_t current_time = time();

The time function should be called with a pointer to a time_t object or
NULL:
time_t time(time_t *tloc);

Fix that first...

but the gcc compiler complains:
error: initializer element is not constant.

.... then (n1124.pdf) 6.7.8-4: "All the expressions in an initializer for an
object that has static storage duration shall be constant expressions or
string literal."

In your case it's a function call.
