System call and DMA blocking
Dear programmers,
I have a problem concerning with the 'system' call.
I am developing an application (APP1) that handle a data acquisition card which make use of a DMA channel. All works fine at this point, but when I try to make from my APP1 a call to 'system("kate&")' to execute a command to start another application, for example, kate KDE editor, then my APP1 block the DMA channel and I need to reset the acquisition card interface to run again my APP1.
I think it is due the system call do a fork, so the new child is a copy of the father process, and therefore the child try to share the DMA channel with the main process.
So, I'd like to know if there any way ( other than 'system' call) to execute/launch another application since my APP1 without blocking the DMA channel. Any suggestions ?
Thanks all,
Jose M.
