I have a program that I have just compiled, in it does execl(emprog[1],"Empire",cnumbuf,"","1","\0377",0); when run it returns a -1 and errno is set to 14. this error is defined as EFAULT Bad Address, for the life of me I can not figure out why I am getting this. I have printf'd all the arguements and they look fine. Any suggestions will be appreciated. I am doing this on 286 xenix 2.2.3 with the 2.2.1 development system.

The 286 will segment fault every time if null is not cast properly. Try casting the terminating null arg to (char *): execl(emprog[1],"Empire",cnumbuf,"","1","\0377",(char *)0); BTW, I'm curious about the "\0377" arg. Does empire have a command line option which takes a 1 char string with -1 as its contents ? -- Dave Hammond daveh@marob.masa.com

Mild brain-blip. Turn that sideways: BTW, I'm curious about the "\0377" arg. Does empire have a command line option which is the 2 char string "^_7" (Ctrl-underscore, "7") ? -- Dave Hammond daveh@marob.masa.com
