Yes, I meant GNULIB_PROGRAM_INVOCATION_NAME, of course. > - If the #ifdef condition is true, you'll be using the > program_invocation_name without having a declaration for it (since > argp-namefrob.h has not been included as this point). Good point. I didn't notice it. > - Programs using the 'error' module are responsible for defining a variable > 'program_name' and initializing it.

Actually, it uses this variable in glibc as well. argp_parse is responsible for setting it. > Can you guarantee that error() will not be invoked before this > initialization? No, of course I cannot. If it is called before argp_parse it will surely coredump. But then, we cannot guarantee that whoever is using this interface will set program_name before calling error(), can we? Regards, Sergey
