SYNOPSIS
     #include <stdlib.h>

     void
     setproctitle(const char *fmt, ...);

DESCRIPTION
     The setproctitle() function sets the invoking process's title.  The pro-
     cess title is set to the last component of the program name, followed by
     a colon and the formatted string specified by fmt. If fmt is NULL, the
     colon and formatted string are omitted.  The length of a process title is
     limited to 2048 bytes.

EXAMPLES
     Set the process title to the program name, with no further information:

           setproctitle(NULL);

     Set the process title to the program name, an informational string, and
     the process ID:

           setproctitle("foo! (%d)", getpid());
