Detailed Description

Temporary block allocator implementation.

Creates pool for block allocation (small ones are done on the stack, bigger using malloc).

The usage is:

// Creates new allocation pool
gp_temp_alloc_create(buf, 3 * 1024);
 
// Make use of it
int *R = gp_temp_alloc_get(buf, 1024);
int *G = gp_temp_alloc_get(buf, 1024);
int *B = gp_temp_alloc_get(buf, 1024);
 
...
 
// Free it
gp_temp_alloc_free(buf);
