API Buffer Error Codes

API Buffer error codes are defined in the ApiBufferErrorCode class. Functions in the ApiBuffer class may return these errors.

Error	Code (Decimal)	Code (Hex)	Description	Resolution
OverMaxLevel	73728	0x12000	Maximum nesting level exceeded.	Implement flow control logic for the API buffer using less nesting levels (currently, up to 100 nesting levels are supported).
InvalidLevel	73729	0x12001	Invalid nesting level. Verify that flow control operations are added to the buffer in the correct order.	Verify that flow control operations are added to the buffer in the correct order.
InvalidBuffControl	73730	0x12002	Invalid control for API buffer. API buffer function cannot be used.	Restart the engine, or restart the PC. Verify that the correct version of the IMDll.dll is used.
InvalidWatchTriggerRoutineChannel	73731	0x12003	Watch trigger routine channel is out of range.	Verify that the watch trigger routine channel is within range.
WatchTriggerRoutineChannelSameAsExecChannel	73732	0x12004	Watch trigger routine channel cannot be the same as the execution channel.	Verify that the watch trigger routine channel is different from the channel the watch is defined for.
RewindFailedFirstCommandOverwritten	73733	0x12005	Failed to rewind. The first command in the buffer was overwritten.	This error is returned if the rewind operation fails because one or more commands in the buffer were overwritten by other commands added to the buffer. To prevent this error, do not add more commands to the buffer after executing the API buffer.
AlreadyRecordingForSpecifiedChannel	73734	0x12006	Already recording API functions for specified channel.	Verify that API functions are not being recorded already for the specified channel.
NotRecording	73735	0x12007	Not recording API functions.	Verify that API functions are being recorded.
RequestModeChangeTimeout	73736	0x12008	Mode change request timed out.	Verify that the API Buffer channel is in a valid state.
ApiBufferNotOpened	73737	0x12009	API buffer is not opened.	Open the API buffer channel by calling the CreateApiBuffer function.
GateNodeHasNoChild	73738	0x1200A	Gate node of multi-condition tree has no child. Gate node cannot be a leaf node.	Make sure to properly connect all the gate note with at least one leaf node as a child. See wmx3Api::ApiBufferMultiCondition::AddGateNode and wmx3Api::ApiBufferMultiCondition::ConnectParentChild.
NotGateNodeHasChildren	73739	0x1200B	Logical not gate node of multi-condition tree has children. Logical not gate node can have only one child.	Make sure not to add or connect multiple children to a logical not gate node.
LeafNodeHasChild	73740	0x1200C	Leaf node of multi-condition tree has child. Leaf node cannot have a child.	Add and connect leaf nodes only using provided methods. See wmx3Api::ApiBufferMultiCondition::AddLeafNode and wmx3Api::ApiBufferMultiCondition::ConnectParentChild.
InvalidMultiCondition	73741	0x1200D	Invalid multi-condition tree; Either the root node is not defined, or there are multiple root nodes, or there is a cycle.	Add and connect nodes only using provided methods. See wmx3Api::ApiBufferMultiCondition::AddGateNode, wmx3Api::ApiBufferMultiCondition::AddLeafNode, and wmx3Api::ApiBufferMultiCondition::ConnectParentChild.
