Executing a new process image completely changes the contents of memory, copying only the argument and environment strings to new locations. Why is absolute zero unattainable? How do computers remember where they store things? I guess if an execv fails it should be there. –Carl Norum Oct 2 '13 at 21:57 Any way of reaching that point is an error...

GNU/Hurd systems have no specific limit on the argument list size, so this error code cannot result, but you may get ENOMEM instead if the arguments are too big for available The new process image has no streams except those it creates afresh. more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed EIO A hard I/O error occurred.

ENOEXEC The specified file can’t be executed because it isn’t in the right format. Together they describe a list of one or more pointers to null-terminated strings that represent the argument list available to the executed program. This macro should only be employed if WIFSTOPPED returned true. //WIFCONTINUED(status) (since Linux 2.6.10) returns true if the child process was resumed by delivery of SIGCONT.

Any ideas why control doesn't return to the parent after the child exits? See Working Directory. Also, the first arg to execv should be an executable file, not a c source file. execvp is a lot nicer since it will look for commands in your PATH setting.

RETURN VALUE A successful call to execv does not have a return value because the new process image overlays the calling process image.
