I'm not sure what you mean by "non-standard file descriptors". The other program is free to open, read, write, etc any file he wants - are you trying to trap any file operation it may want to do? You *could* do such things -google for "code injection" and "API hooking"- but I doubt it's what you really want. -- Gabriel Genellina Softlab SRL Hi Gabriel! When I wrote "non-standard file descriptors", I meant the file descriptior which are pointed to files in the hardrive. What I would like to do is not to trap any file operation, but instead intercept that file operation, i.e. I would like the output of the external program to don't be writen in a file (its normal behavior), but instead be sent to any variable in my program. I know the name of the file where the external program will write the output. I pass its name along the command line.
