55 | <p>SDL_perl is a package of perl modules that provides both functional and object orient |
56 | interfaces to the Simple DirectMedia Layer for Perl 5. This package does take some |
57 | liberties with the SDL API, and attempts to adhere to the spirit of both the SDL |
58 | and Perl. This document describes the low-level functional SDL_perl API. For the |
59 | object oriented programming interface please see the documentation provided on a |
60 | per class basis.</p> |

69 | <p>As with the C language API, SDL_perl initializes the SDL environment through |
30652763 |
70 | the <code>SDL::init</code> subroutine. This routine takes a mode flag constructed through |
71 | the bitwise OR product of the SDL_INIT_* constants.</p> |
72 | <p>The constants are not exported by default. You can export them into your namespace by doing:</p> |
73 | <pre> use SDL ':all'; |
74 | |
75 | </pre> |
76 | <p>or access them directly:</p> |
