/*
* tableAddress identifies the target dynamic-function-table header. Records
* are returned in caller-provided storage as contiguous target-native
* RUNTIME_FUNCTION bytes. The callee never allocates output storage, and the
* caller-provided buffer does not require any particular alignment.
*
* bytesNeeded and entries are required outputs that are initialized and
* reported on every valid call. A null buffer with a zero bufferSize queries
* the required size. If the buffer is too small, no data is written,
* bytesNeeded and entries report the required byte and record counts, and
* the method returns S_FALSE. If the buffer is large enough, the complete
* table is written and the method returns S_OK. An empty or unmatched table
* returns S_OK with bytesNeeded and entries both set to zero.
*
* Target memory is an immutable snapshot between IXCLRDataProcess::Flush
* calls, so repeated calls before Flush are idempotent. The caller must call
* Flush after changing the data target.
