RE: IFS Open

["Bartell, Aaron L. (TC)" <ALBartell@xxxxxxxxxxxxxx>]

To go along with Scott and Joe's comments I am fairly certain you cannot
use a VARYING field as a parm to a C API.  This is because the first two
chars of the variable contain it's length and since C doesn't support
RPG's version of VARYING length fields it thinks those first two bytes
are part of the file path/name.

I may be wrong, but I struggled with this some time ago and I think that
is what I came up with.

Subject: IFS Open

When using an IFS open like this (I'm using Scott's prototype):

fd = open('/michael/cattest' : flags);

all is good. However, when I put the same value in a variable (FileName)
and use it like this:

D FileName        S           1024    Varying 
fd = open(FileName : flags);          

I receive an fd of -1 and the message "open() for input: No such path or
directory." I've tried a bunch of different combinations and can't make
it work.

Please help the stoopid guy in the corner. You'll fill your random act
of kindness quotient for the day.

TIA...
