NAME

       gg-error, gii-error, ggi-error - GGI error definitions

SYNOPSIS

       #include <ggi/errors.h>

DESCRIPTION

       GGI return code policy is usually (unless otherwise noted):

       == 0 on normal completion
        > 0 when giving additional hints or returning positiv integer data
        < 0 for errors

       GGI error codes are of the form GGI_* and are guaranteed to be negative
       (except GGI_OK of course, which is guaranteed to be zero).

       The following error codes are defined:

       GGI_OK                  0     /* All is well */

       GGI_ENOMEM            -20     /* Out of memory */
       GGI_ENOFILE           -21     /* File does not exist */
       GGI_ENODEVICE         -22     /* Input/Output device can not be opened */
       GGI_EARGREQ           -23     /* Required argument missing */
       GGI_EARGINVAL         -24     /* Invalid argument(s) */
       GGI_ENOTALLOC         -25     /* Trying to use or deallocate a resource that
                                        was not previously allocated */
       GGI_EFATAL            -26     /* Fatal error - the state of the target of
                                        the operation is undefined */
       GGI_EBADFILE          -27     /* Error reading (config) file */
       GGI_ENOSPACE          -28     /* Out of space / range */
       GGI_ENOFUNC           -29     /* Function not implemented */
       GGI_EBUSY             -30     /* Object is busy */
       GGI_ENOTFOUND         -31     /* The requested object was not found */
       GGI_EEXCLUSIVE        -32     /* Tried to get non-exclusive access to object
                                        which only supports exclusive access */
       GGI_ENOMATCH          -33     /* No matching entry found */

       GGI_EEVUNKNOWN        -40     /* Unknown event sent to or received from
                                        input source */
       GGI_EEVNOTARGET       -41     /* No apropriate target for for sent event */
       GGI_EEVOVERFLOW       -42     /* Overflow when queuing event */

       GGI_EUNKNOWN          -99     /* Unknown error */

       The values -1 to -19 are  reserved  for  extensions.  See  their  error
       manpage for the details.
