NAME

       SDL_rand - Generate a pseudo-random number less than n for positive n

HEADER FILE

       Defined in SDL3/SDL_stdinc.h

SYNOPSIS

       #include "SDL3/SDL.h"

       Sint32 SDL_rand(Sint32 n);

DESCRIPTION

       The  method  used  is  faster and of better quality than rand()%n . Odds are roughly 99.9% even for n = 1
       million. Evenness is better for smaller n, and much worse as n gets bigger.

       Example: to simulate a d6 use SDL_rand(6)+1 The +1 converts 0..5 to 1..6

       If you want to generate a pseudo-random number in the full range of

       Sint32 , you should use: ( Sint32 ) SDL_rand_bits ()

       If you want reproducible output, be sure to initialize with

       SDL_srand () first.

       There are no guarantees as to the quality of the random sequence produced, and this should  not  be  used
       for  security  (cryptography,  passwords)  or where money is on the line (loot-boxes, casinos). There are
       many random number libraries available with different characteristics and you should pick one of those to
       meet any serious needs.

FUNCTION PARAMETERS

       n      the number of possible outcomes. n must be positive.

RETURN VALUE

       ( Sint32 ) Returns a random value in the range of [0 .. n-1].

THREAD SAFETY

       All calls should be made from a single thread

AVAILABILITY

       This function is available since SDL 3.2.0.
