Associated Macros

These macros are defined for internal use by the flag service.
ADI_FLAG_CREATE_FLAG_ID
ADI_FLAG_GET_BIT
ADI_FLAG_GET_OFFSET
ADI_FLAG_GET_MASK

ADI_FLAG_RESULT

Each API function of the flag service returns an
enumeration as a return code. As with all system services, generic success is
defined as 0 and generic failure is defined as 1. This allows the calling
function to quickly evaluate the return code for a zero or nonzero value.
All detailed result codes for the flag service begin with the value
ADI_FLAG_ENUMERATION_START
Result code
ADI_FLAG_RESULT_SUCCESS=0
ADI_FLAG_RESULT_FAILED=1
ADI_FLAG_RESULT_INVALID_FLAG_ID
ADI_FLAG_RESULT_INTERRUPT_MANAGER_ERROR
ADI_FLAG_RESULT_ERROR_REMOVING_CALLBACK
ADI_FLAG_RESULT_ALL_IN_USE
ADI_FLAG_RESULT_PORT_CONTROL_ERROR
