# - Script to check if the signature for a mac HID callback uses UInt32 or uint32_t
|
||
|
|
# Requires that the associated CPP file be present: CheckMacHIDAPI.cpp.
|
||
|
|
#
|
||
|
|
# MACOSX_HID_UINT32T, set according to the results of our test.
|
||
|
|
#
|
||
|
|
# Use add_definitions(-DMACOSX_HID_UINT32T=${MACOSX_HID_UINT32T}) in your
|
||
|
|
# listfile and the following prototype for the function you'd like to
|
||
|
|
# register using setInterruptReportHandlerCallback:
|
||
|
|
# void ReaderReportCallback(
|
||
|
|
# void *target,
|
||
|
|
# IOReturn result,
|
||

# MACOSX_HID_UINT32T size
