NAME
aa_parseoptions - parse the standard command line options used by AA- lib.
SYNOPSIS
#include <aalib.h> int aa_parseoptions ( struct aa_hardware_params *p, aa_renderparams *r, int *argc, char **argv );
PARAMETERS
struct aa_hardware_params *p Hardware parameters structure to alter. It is expected that this structure only with necessary modifications will be later used to initialize the AA-lib context. aa_renderparams *r Rendering prameters structure to alter. It is expected that this structure only with necessary modifications will be later used to render images. int *argc Pointer to argc parameter passed to function "main". char **argv Pointer to argv parameter passed to function "main".
DESCRIPTION
Use this function to parse the standard command line options used by AA-lib. Every AA-lib program ought to call this function to let user specify some extra parameters. The function alters the aa_hard‐ ware_params and aa_renderparams structures and removes known options from the argc/argv lists. It also parse the AAOPTS environment vari‐ able. When called with NULL for the argc/argv parameters, it parses AAOPTS only. At least this call ought to be in every AA-lib program.
RETURNS
1 when sucesfull and 0 on failure. The program then can print the help text available in aa_help variable. aa_fonts(3), aa_dither‐ aa_mousedrivers(3), aa_displayrecommended(3), aa_scrwidth(3), aa_imgwidth(3), aa_attrs(3), aa_current‐ aa_autoinitmouse(3), aa_initkbd(3), aa_uninitmouse(3), aa_gotoxy(3), aa_hidemouse(3), aa_setfont(3), aa_resizehandler(3), aa_putpixel(3), aa_recom‐ aa_recommendhimouse(3), aa_recom‐ aa_recommendlowdisplay(3)
