This (untested) SHOULD work fine. function create_my_bmap (BMAP* this)
{
BMAP* fb = bmap_createblack(256,256,24);
BMAP* this;
wait(1);
// do something with fb
...
//
wait(1);
this = fb;
BMAP* that = fb;
//is now done! both "this" and "that" and "fb" are ALL pointing at SAME bmap.
}
But I would try to avoid this type of programming, its going to be very easy to end up with "invalid pointer" errors.

Oh crud! Sorry, Ignore my previous post. I didnt notice that "this" was arriving as a parameter....
Spirits first looks good to me...
The second one will only work if there is NO waits in there. And I believe XD1v0 needed them in there.

The second one will only work if there is NO waits in there. And I believe XD1v0 needed them in there. You understand rightly, i need use wait in function. I want do something like this.
#include <acknex.h>
#include <default.c>
PANEL* cool_pan =
{
scale_x = 0.5; scale_y = 0.5;
flags = SHOW;
}
function create_screen_bmap (BMAP* this,VECTOR* pos,VECTOR* aang)
{
BMAP* fb = bmap_createblack(screen_size.x,screen_size.y,24);
vec_set(camera.x,pos);vec_set(camera.pan,aang);
wait(1);// render screen in new position and angle
bmap_for_screen(fb,0,1);
this = fb;
}
void main ()
{
level_load(0);ent_create("sphere.mdl",nullvector,NULL);
create_screen_bmap(cool_pan.bmap,vector(-50,0,0),nullvector);beep();
// I want render screen into panel.bmap, but this dont work
}

BMAP* fb = bmap_createblack(screen_size.x,screen_size.y,24); var vHandle; vHandle = handle(fb); // put waits in here until you are fine  fb = ptr_for_handle(vHandle); bmap_for_screen(fb,0,1);
no science involved

i managed to get the screen capture but the black bitmap is overlaying the bitmap. see image below: 
#include <acknex.h>
#include <default.c>
BMAP* panel_created;
PANEL* cool_pan =
{
scale_x = 0.5; scale_y = 0.5;
//bmap = temp_bmap;
flags = SHOW;
alpha = 100;
}
function create_screen_bmap (VECTOR* pos,VECTOR* aang)
{
panel_created = bmap_createblack(screen_size.x,screen_size.y,24);
//vec_set(camera.x,pos);
//vec_set(camera.pan,aang);
wait(1);// render screen in new position and angle
bmap_for_screen(panel_created,0,1);
wait(1);
//this = fb;
//panel_created = fb;
}
void main ()
{
level_load("arena.wmb");
wait(2);
create_screen_bmap(vector(0,0,0),nullvector);
cool_pan->bmap = panel_created;
cool_pan->flags = SHOW;
wait(1);
beep();
// I want render screen into panel.bmap, but this dont work
}

ok FIXED.. a wait(1) was missing to update the bitmap. here is the (tested) code:
#include <acknex.h>
#include <default.c>
BMAP* panel_created;
PANEL* cool_pan =
{
scale_x = 0.5; scale_y = 0.5;
flags = SHOW;
alpha = 100;
}
function create_screen_bmap (VECTOR* pos,VECTOR* aang)
{
panel_created = bmap_createblack(screen_size.x,screen_size.y,24);
vec_set(camera.x,pos);
vec_set(camera.pan,aang);
wait(1);// render screen in new position and angle
bmap_for_screen(panel_created,0,1);
wait(1);
}
void main ()
{
level_load("arena.wmb");
wait(2);
create_screen_bmap(vector(0,0,0),nullvector);
wait(1);
cool_pan->bmap = panel_created;
cool_pan->flags = SHOW;
wait(1);
beep();
// I want render screen into panel.bmap, but this dont work
}
make sure ur camera is facing wat u want to take screenshot.
