Hi,
I need to use an atomic pointer for my app. The documentation for the glib
atomic operations is not exactly helpful.
Anyway, I wrote a test program:
----8<----
/* atomic.c */
#include <glib.h>
int main()
{
char* myptr = 0;
char* str = "Hello";
g_atomic_pointer_set(&myptr, str);
char* p = g_atomic_pointer_get(&myptr);
return 0;
}
----8<----
I had to use the output of
gcc `pkg-config --cflags glib-2.0` atomic.c -E
to understand what was meant to be used as the parameters. Anyway, the
output of this does not look at all atomic: (not that i'm any expert)
----8<----
...
# 4 "atomic.c" 2
int main()
{
char* myptr = 0;
char* str = "Hello";
((void) (*(&myptr) = (str)));
char* p = ((gpointer)*(&myptr));
return 0;
}
----8<----
This is on a x86_64, running Gentoo, glib-2.20.5.
I don't know if I've got the idea right for how these functions are
supposed to be used. Any ideas?
Cheers,
james.
