bionic (3) al_get_cpu_count.3alleg5.gz

NAME

       al_get_cpu_count - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              int al_get_cpu_count(void)

DESCRIPTION

       Returns the number of CPU cores that the system Allegro is running on has and which could be detected, or
       a negative number if detection failed.  Even if a positive number is returned, it might be that it is not
       correct.   For  example,  Allegro running on a virtual machine will return the amount of CPU's of the VM,
       and not that of the underlying system.

       Furthermore even if the number is correct, this only gives you information about the total CPU  cores  of
       the  system  Allegro  runs  on.   The  amount  of  cores  available  to  your  program may be less due to
       circumstances such as programs that are currently running.

       Therefore, it's best to use this for advisory purposes only.  It is certainly a bad  idea  to  make  your
       program exclusive to systems for which this function returns a certain "desirable" number.

       This function may be called prior to al_install_system(3alleg5) or al_init(3alleg5).
