thanks simon, my program is working fine. i have another doubt about passing file descriptors. if i have a file something like this in the parent program, how can i pass this descriptor to the child process ?? main() { FILE *fprt; char f_path_name[] = "mylib/myfile(my_member)"; fprt = fopen(f_path_name,"w"); .... spawn(); ..... } how do i convert fptr to a string so that i can pass it to spawn(). i believe fptr is a pointer to a structure. rgds., srikanth d > ---------- > From: Simon Coulter[SMTP:shc@flybynight.com.au] > Reply To: c400-l@midrange.com > Sent: Tuesday, April 16, 2002 3:00 PM > To: c400-l@midrange.com > Subject: Re: [C400-L] spawn() problem > > > Srikanth_D wrote: > child_pid = spawn(pgm_nam, > 0, > NULL, > &inherit, > NULL, <====== This cannot be NULL > envVars); > > The description of the fifth parameter is: > "argv[] > (Input) An array of pointers to strings that contain the argument list for > the executable file.
