The IOC_CONVERT_FROM macro is used to see if the contents of the current M_IOCTL message had its origin in a different C Language Type Model.

The IOC_CONVERT_FROM() function returns the following values:

IOC_ILP32 This is an LP64 kernel and the M_IOCTL originated in an ILP32 user process.

IOC_NONE The M_IOCTL message uses the same C Language Type Model as this calling module or driver.

The IOC_CONVERT_FROM() macro can be called from user, interrupt, or kernel context.
