Communication with C/C++ program

yixin · 07-08-2009, 01:23 AM

I`m in a software project in which we will use FTP server.
In this project we want the server send my C/C++ program a signal when a client upload a file.

Is there a script to realize this fonction?

thanks~

About the signal, I dont konw how to say exactly. Genarally, it could be any way that my program on the same PC of the server can konw someone has upload a file without scanning the disk of the FTP server.

ioFTPD can execute your program on event OnUploadComplete.

Code:

[Events]
OnUploadComplete = EXEC path\to\your\program.exe
...

in this case ioFTPD will pass next arguments to you program:

Code:

phisical\path\of\the\uploaded\file
CRC32 sum of the file being uploaded
virtual\path\of\the\uploaded\file

This is very useful

P.S. Where can I fine the exact definition of the input arguments? I can'nt find them out in the changelog.txt

i have no idea if there is a manual for that.
i usually use foreach loop trough inputs args, to see what is there.

u have also ioFTPD environmnet variables (PATH, USER, SPEED, ...) available in your program. u can find them in /etc/ folder i think.

just use a method as if u were looking for some WINDOWS ENV variable.

Code:

windows:
Environment.GetEnvironmentVariable("windir");
...

ioFTPD:
Environment.GetEnvironmentVariable("USER"); //username of the user who uploaded the file
Environment.GetEnvironmentVariable("SPEED"); //average speed the file was uplaoded with
...

here is also nice example to start with:
