Use
The purpose of this call is to load a floating point context with a specified set of register and FPSR values, destroying any pending or incompletely processed exception in the process.
Notes
This call should almost always be preceded by one to FPEmulator_Abort you can create chaos in the floating point system by calling FPEmulator_LoadContext while there is a pending or incompletely processed exception.
Contexts are only available from FPEmulator 4.12 and later.
This call did not work correctly until version 4.17 of the FPEmulator module.
