Detailed Description

Type definitions related to the Guacamole protocol.

Enumeration Type Documentation

enum guac_composite_mode

Composite modes used by Guacamole draw instructions.

Each composite mode maps to a unique channel mask integer.

enum guac_protocol_status

Set of all possible status codes returned by protocol operations.

These codes relate to Guacamole server/client communication, and not to internal communication of errors within libguac and linked software.

In general:

0x0000 - 0x00FF: Successful operations.
0x0100 - 0x01FF: Operations that failed due to implementation status.
0x0200 - 0x02FF: Operations that failed due to environmental.
0x0300 - 0x03FF: Operations that failed due to user action.

There is a general correspondence of these status codes with HTTP response codes.

Enumerator:

GUAC_PROTOCOL_STATUS_SUCCESS	The operation succeeded.
GUAC_PROTOCOL_STATUS_UNSUPPORTED	The requested operation is unsupported.
GUAC_PROTOCOL_STATUS_SERVER_ERROR	The operation could not be performed due to an internal failure.
GUAC_PROTOCOL_STATUS_SERVER_BUSY	The operation could not be performed due as the server is busy.
GUAC_PROTOCOL_STATUS_UPSTREAM_TIMEOUT	The operation could not be performed because the upstream server is not responding.
GUAC_PROTOCOL_STATUS_UPSTREAM_ERROR	The operation was unsuccessful due to an error or otherwise unexpected condition of the upstream server.
GUAC_PROTOCOL_STATUS_RESOURCE_NOT_FOUND	The operation could not be performed as the requested resource does not exist.
GUAC_PROTOCOL_STATUS_RESOURCE_CONFLICT	The operation could not be performed as the requested resource is already in use.
GUAC_PROTOCOL_STATUS_CLIENT_BAD_REQUEST	The operation could not be performed because bad parameters were given.
GUAC_PROTOCOL_STATUS_CLIENT_UNAUTHORIZED	Permission was denied to perform the operation, as the user is not yet authorized (not yet logged in, for example).
GUAC_PROTOCOL_STATUS_CLIENT_FORBIDDEN	Permission was denied to perform the operation, and this permission will not be granted even if the user is authorized.
GUAC_PROTOCOL_STATUS_CLIENT_TIMEOUT	The client took too long to respond.
GUAC_PROTOCOL_STATUS_CLIENT_OVERRUN	The client sent too much data.
GUAC_PROTOCOL_STATUS_CLIENT_BAD_TYPE	The client sent data of an unsupported or unexpected type.
GUAC_PROTOCOL_STATUS_CLIENT_TOO_MANY	The operation failed because the current client is already using too many resources.

enum guac_transfer_function

Default transfer functions.

There is no current facility in the Guacamole protocol to define custom transfer functions.
