Hello people:
Is there an API that can act like the File Transfer Agent which i can use to include file transfering in my applications whithout the need to use external programs?
edit: I meant an API for C/C++/Java or another language, I'd prefer to have it in C++ since our apps are written in C++
thanks
Carlos

MQ is not really a "file transfer" system. It's a messaging system.
It's much better for your programs to write messages directly to MQ than to write them to files, and then have to try and move the files.

well jeff, i know that, but i also know that if you combine the reasonably powerful security of MQ you can get a very secure file transfer system, specially when MQ is your only option for communications, the problem is a special netadmin who won't allow us to use ftp across the network in which we are coding our programs, so there's not much of a choice there, and if i was to write binary data messages how can i then transport them back to a file?

Message data is just a big long buffer of data. That data can be written to a file or read from a file without regard for whether the data is binary, or text. One just needs to indicate that the message data should be treated as string data if it's text, or not treated as string data if it's not. MQFMT_STRING or MQFMT_NONE, basically.
Also, MQ does have a reasonably good set of security for certain things... but it may not be sufficient for a full scale Enterprise File Transfer system. I'm not saying "don't use MQ to move files", I'm just saying "make sure you know what your actual requirements for moving files is, first".
The presupplied file transfer program that comes with MQ does things like automatically segment files into smaller messages and reassemble messages into a larger file. It does a few other things that you'll otherwise have to write yourself.
There is not a presupplied API, nor sample code, AFAIK that you can include or use in your program to accomplish all the same things. You'll have to write it by hand - or use system()...

well guess what, that solved it, thanks a lot jeff, didn't know exactly what the mqfmt thingy was doing and well, it was taking the binary data and passing it as string, so there it must have been losing some special chars
