Method for reading in command line options

Just wondering if there is a tried and true method for reading in command line options/flags. Are there funcitons out there for searching argv? I could write one myself, but I was just wondering if any documentation existed on this topic.

Thanks,

Jake

None that I am aware of, but that does not mean much. :-)

Try this,

if( argc > 1 )
{
int x, r;
for( x = 1; x < argc; x++ )
{
r = options( argv[x] );
if( !r )
printf("\nUnrecognized switch.\n\n");
}
}

...

int options( char* args )
{
int r = 0;

if( strlen( args ) > 2 && args[0] == '-' )
return r;

switch( tolower( args[1] ) )
{
case 'd':
//insert code here
r = 1;
break;
default:
break;
}

return r;
}

Simply add more case statements to add additional flags.

Nothing has happened on this question in more than 10 months. It's time for cleanup!

My recommendation, which I will post in the Cleanup topic area, is to
split points between akshayxx and snewo.
