MTMICRGetKeyCount
MTMICRGetKeyCount function returns the number of keys that belong to a section with the name specified in variable
pcSection. The function MTMICRGetKeyCount parses through a null terminated string which contains a set of key/value
pairs. The key/value pairs get stored in the buffer using function MTMICRSetValue or MTMICRSetIndexValue.
ULONG MTMICRGetKeyCount (
char *pcData,
char *pcSection,
DWORD *pdwKeyCount
);
