Title The format for the print file generated by printOpen
Ref. No. QNX.000006990
Category(ies) Development
Issue I am writing an application to print the screen.
I need to know, what is the format of print_file (the output file generated by printOpen()). 

The code I am using is:
print_fp = PrintOpen("/app/snapapp/print_file", x09  200 400)
PrintScreen (print_fp, NULL);
PrintClose(print_fp);



Solution The format of the file is defined in /windows/include/qwprint.h.
Further information can be found in wind_struct.h.

Also, if you are looking for source code examples, you can look on our free software section and find:
/usr/free/qnx4/qwindows/contrib
pictps.tgz
and
picthp.tgz

These are both Qwindows programs to read these files and convert them.
