aa_parseoptions(3) Introduction to Library Functions aa_parseoptions(3)
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.
