Function Documentation

int _eurephia_getopt	(	const char *	module,
		int *	curarg,
		int	argc,
		char **	argv,
		e_options *	argopts
	)

Internal argument parser. Normally called via the eurephia_getopt(...) macro. Parses an argument and prepares the char **optargs array with parameters to the arguments.

Parameters:

	module	string (const char *) containing a descriptive module name, used in error situations.
	curarg	pointer to the argument index counter which gets updated during parsing.
	argc	Input argument counter
	argv	Input argument array (char **)
	argopts	e_options struct array containing valid argument

Returns:

returns the short arg value on success, or -1 on failure.

size_t eurephia_arraycp	(	int	stidx,
		int	inargc,
		char **	inargv,
		char **	outargv,
		size_t	outsize
	)

This function will take (argc,argv) and copy pointers over to (**outargv), starting from the index given in stidx (start index). The outargv array must have been allocated first by calloc(sizeof(char *), elmnts). The outsize must not exceed the number of elements you have allocated space for. The function returns number of elements copied (the new argc, kind of)

Parameters:

	stidx	start index of where to start the copy
	inargc	input argument counter (size of the input array)
	inargv	input argument array (char **)
	outargv	pointer to an array of where to put the values being copied.
	outsize	Size of the output array.

Returns:

Returns number of argument copied over to the output array.

char* optargs[64]

If an argument takes parameters, they will be put into this array
