Title: mallocs in game time
Post by: RandomTiger on June 01, 2003, 09:45:52 am

There are a fair few mallocs happening in game time.
Put a flag in game_frame() and check it in vm_malloc to get details.

Memory allocation - allocates space to a block of specified size and retunrs the pointer to the first allocated byte.  Returns null pointer if no available space.

sound.cpp with ds.cpp and animplay.cpp are all guilty.

Allocates memory space for storage of variables (i.e. values used by the program).  I remember using it doing some C programs for LLP at uni (albeit only for a semester).

mallocs aren't that bad, compared to large amounts of static arrays, which cause of-so-many cache misses (*points at current decal code*). Remember that the faster the processor is, the more impact a cache-miss has.
