/* NAME
/* mail_task 3
/* SUMMARY
/* set task name for logging purposes
/* SYNOPSIS
/* #include <mail_task.h>
/*
/* const char *mail_task(argv0)
/* const char *argv0;
/* DESCRIPTION
/* mail_task() enforces consistent naming of mailer processes.
/* It strips pathname information from the process name, and
/* prepends the name of the mail system so that logfile entries
/* are easier to recognize.
/*
/* The result is volatile. Make a copy of the result if it is
/* to be used for any appreciable amount of time.
/* LICENSE
/* .ad
