/**
|
|
* @brief Invokes an arbitrary function pointer at runtime using a generic
|
|
* argument array.
|
|
*
|
|
* @param pFunctionAddress Pointer to the target function. Must not be NULL;
|
|
* passing NULL causes an immediate return of 0.
|
|
* @param dwArgCount Number of entries in @p pArgs. May be 0 for
|
|
* zero-argument calls.
|
|
* @param pArgs Array of @p dwArgCount UINT_PTR-sized arguments.
|
|
* Ignored (and may be NULL) when @p dwArgCount is 0.
|
|
*
|
|
* @return The value returned by the invoked function as a UINT_PTR, or 0 if
|
|
* @p pFunctionAddress is NULL or the current architecture is unsupported.
|
|
*
|
|
* @note Callee-saved registers (RBX, RBP, RDI, RSI, R12-R15) are preserved
|
|
* by the assembly bridge. The caller is responsible for ensuring that
|
|
* the argument types and count are compatible with the target function.
