Function Documentation
◆ _fxrstor()
|
static |
Restores the XMM, MMX, MXCSR and x87 FPU registers from the 512-byte memory region pointed to by the input parameter __p.
The contents of this memory region should have been written to by a previous _fxsave or _fxsave64 intrinsic.
This intrinsic corresponds to the FXRSTOR instruction.
- Parameters
-
__p A pointer to a 512-byte memory region. The beginning of this memory region should be aligned on a 16-byte boundary.

- Parameters
-
__p A pointer to a 512-byte memory region. The beginning of this memory region should be aligned on a 16-byte boundary.
