NAME

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

#include <ggi/errors.h>

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.
