Layout

The COVERAGE_MODULE_REQUEST is 0x14 or 0x18 bytes in 32-bit and 64-bit Windows, respectively.

COVERAGE_REQUEST_CODES RequestType;

union {
    UCHAR MD5Hash [0x10];
    UNICODE_STRING ModuleName;
} SearchInfo;

While the COVERAGE_REQUEST_CODES enumeration seems to be used nowhere else, it may as well be presented here:

• 0 for CoverageAllModules;
• 1 for CoverageSearchByHash;
• 2 for CoverageSearchByName.
