Routine Name:
GetContext
Routine Description:
Read Context - Read a set of CPU / Co-Proc registers that define the state of the target
The CONTEXT.RegGroupSelection bitfield allow to select which group of register need to be read only
Argument(s):
pContext - Return context (CPU dependant structure).
Note: The context is also passed in to indicate only the RegGroupSelection (which reg groups are read)
Return Value:
Error status:
S_OK: Function successful
EXDI_E_CANNOTWHILETGTRUNNING Cannot proceed while target running. Must halt the target first.
Note: this error is generated only if the probe / target does not support this operation "on the fly".
see DEBUG_ACCESS_CAPABILITIES_STRUCT.fReadRegWhileRunning
EXDI_E_NOTIMPL: Not implemented
EXDI_E_OUTOFMEMORY: Failed to allocate necessary memory
EXDI_E_INVALIDARG: One or more arguments are invalid
EXDI_E_ABORT: Operation aborted
EXDI_E_FAIL: Unspecified failure
EXDI_E_COMMUNICATION: Communication error between host driver and target
EXDI_E_USEDBYCONCURENTTHREAD: Cannot proceed immediately because resource is already used by concurent thread.
