EX_getArg Function (ROM Call 0xBE)

args.h

ESI EX_getArg (short n);

Returns a pointer to the nth argument.

EX_getArg is TIOS function which may be useful if you want to access arguments in non_sequential order. EX_getArg returns a pointer to the argument which ordinal number is n (which may be later processed using GetIntArg etc.). Arguments are numbered from zero (i.e. 0, 1, 2, ... N-1 where N is the total number of arguments). Note that when n = N, EX_getArg returns NULL, and when n > N, EX_getArg throws an error, so it is good idea to check in advance the total number of arguments using ArgCount.
