NAME

6       al_get_cpu_count - Allegro 5 API
7

SYNOPSIS

9              #include <allegro5/allegro.h>
10
11              int al_get_cpu_count(void)
12

DESCRIPTION

14       Returns  the  number of CPU cores that the system Allegro is running on
15       has and which could be detected, or  a  negative  number  if  detection
16       failed.   Even if a positive number is returned, it might be that it is
17       not correct.  For example, Allegro running on a  virtual  machine  will
18       return  the  amount  of CPU’s of the VM, and not that of the underlying
19       system.
20
21       Furthermore even if the number is correct, this only gives you informa‐
22       tion  about  the  total  CPU  cores of the system Allegro runs on.  The
23       amount of cores available to your program may be less  due  to  circum‐
24       stances such as programs that are currently running.
25
26       Therefore,  it’s  best  to  use this for advisory purposes only.  It is
27       certainly a bad idea to make your  program  exclusive  to  systems  for
28       which this function returns a certain “desirable” number.
29
30       This   function   may   be  called  prior  to  al_install_system(3)  or
31       al_init(3).
