Arguments

 

file_spec

   The full file specification of a new image to be activated in the
   child process.
 

arg0, ...

   A sequence of pointers to null-terminated character strings.

   If the POSIX-1 format is used, at least one argument must be
   present and must point to a string that is the same as the new
   process filename (or its last component). (This pointer can also
   be the NULL pointer, but then execle would accomplish nothing.)
   The last pointer must be the NULL pointer. This is also the
   convention if the compatibility format is used.
