libkemo-m104: M104_open

SYNOPSIS

       #include <M104.h>  -lkemo-m104
       int M104_open(const char *port, ...);

DESCRIPTION

       The M104_open function opens the specified channels on the
       M104 device, attached to the specified port parameter.
       The  port  parameter  is a string naming the parallel port
       the device is attached to. The values can be:
        "lp0", "lp1" or "lp2"
       The channels are given as digits in  the  NULL  terminated
       list.
       The channels values are in the range 1,..., 4.
       M104_ALL can also be used as a shorthand for all channels.
       The channels to be opened will be added as  long  as  they
       are in the valid range.

RETURN VALUE

        Upon  successful  completion M104_open returns 0.  Other­
       wise, -1 is returned, the global variable errno is set  to
       indicate  the error and an error message is issued to sys­
       log at LOG_PID and LOG_ERR facilities
