This intrinsic inserts a
CLREX instruction into the instruction stream generated by the compiler.
It enables you to include a
CLREX instruction in your C or C++ code.
The compiler does not recognize the
__clrex intrinsic when compiling for a
target that does not support the
CLREX instruction. The compiler generates
either a warning or an error in this case, depending on the source language:
- In C code:
Warning: #223-D: function "__clrex" declared implicitly.
- In C++ code:
Error: #20: identifier "__clrex" is undefined.
