Hi,
I posted this email a short while ago, and got some great tips for
accessing /proc/self/status to read the process name. However, guess
what I just found (after I've finished and tested my /proc/
implementation?)
man 3 program_invocation_short_name:
NAME
program_invocation_name, program_invocation_short_name - obtain name
used to invoke calling program
...
DESCRIPTION
program_invocation_name contains the name that was used to invoke the
calling program. This is the same as the value of argv[0] in main(),
with the difference that the scope of program_invocation_name is
global.
cool! Oh well, reading /proc/ was an experience :)
