    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.
