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_hardware_params and aa_renderparams structures and removes known options from
the argc/argv lists. It also parse the AAOPTS environment variable. 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.
