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_render-
params 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 parame-
ters, 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.
