MTMICRGETSECTIONCOUNT
MTMICRGetSectionCount function returns the number of section present in a null terminated buffer which contains a set of
key/value pairs. The key/value pairs get stored in the buffer using function MTMICRSetValue or MTMICRSetIndexValue.
ULONG MTMICRGetSectionCount (
char *pcData,
DWORD *pdwSectionCount
);
