hello all,

I am trying to snapshot the xwindows screen by writing a program in 'C' language.

I don't know how to proceed....
Is there any system call to capture the screen to an image

There was a program bundled with X ages ago that took screen caps. I guess it was written in C or C++. I just can't remember the name.

You could make a system call to use the 'import' command (you need to have ImageMagick installed for this) and just format the command: import -window root name_of_image.png - the '-window root' bit means that it takes a screenshot of your whole desktop, not just a window. You can also make it save in different file formats by changing the extension, it'll do the rest.

TTFN,
