    NAME

    ieee1284_claim - claim access to the port
     
    

    SYNOPSIS

    #include <ieee1284.h>

    int ieee1284_claim (struct parport *port);

     

    DESCRIPTION

    With the exception of ieee1284_get_deviceid(3), ieee1284_claim must be called on an open port before any other libieee1284 function for accessing a device on it.

     

    RETURN VALUE

    E1284_OK
    Success. Note that, unless the F1284_EXCL flag was specified to start with, the port should be released within a ``reasonable'' amount of time.

    E1284_NOMEM
    There is not enough memory.

    E1284_INVALIDPORT
    The port parameter is invalid (for instance, it might not have been opened yet).

    E1284_SYS
    There was a problem at the operating system level. The global variable errno has been set appropriately.
