7       lib.

SYNOPSIS

10       #include <aalib.h>
11
12       int aa_parseoptions
13       (
14            struct aa_hardware_params *p,
15            aa_renderparams *r,
16            int *argc,
17            char **argv
18       );
19

PARAMETERS

21       struct aa_hardware_params *p
22              Hardware parameters structure to alter. It is expected that this
23              structure  only  with necessary modifications will be later used
24              to initialize the AA-lib context.
25
26       aa_renderparams *r
27              Rendering prameters structure to alter. It is expected that this
28              structure  only  with necessary modifications will be later used
29              to render images.
30
31       int *argc
32              Pointer to argc parameter passed to function "main".
33
34       char **argv
35              Pointer to argv parameter passed to function "main".

DESCRIPTION

38       Use this function to parse the standard command line  options  used  by
39       AA-lib.  Every  AA-lib  program ought to call this function to let user
40       specify some  extra  parameters.   The  function  alters  the  aa_hard‐
41       ware_params  and  aa_renderparams  structures and removes known options
42       from the argc/argv lists. It also parse the  AAOPTS  environment  vari‐
43       able.   When  called  with NULL for the argc/argv parameters, it parses
44       AAOPTS only. At least this call ought to be in every AA-lib program.
45

RETURNS

47       1 when sucesfull and 0 on failure. The program then can print the  help
48       text available in aa_help variable.
