Members

SizeOfStruct

The size of this structure, in bytes.

Flags

This member can be one of the following values.

Value	Meaning
IMAGEHLP_GET_TYPE_INFO_CHILDREN 0x00000002	Retrieve information about the children of the specified types, not the types themselves.
IMAGEHLP_GET_TYPE_INFO_UNCACHED 0x00000001	Do not cache the data for later retrievals. It is good to use this flag if you will not be requesting the information again.

NumIds

The number of elements specified in the TypeIds array.

TypeIds

An array of type indexes.

TagFilter

The filter for return values. For example, set this member to 1 << SymTagData to return only results with a symbol tag of SymTagData. For a list of tags, see the SymTagEnum type defined in Dbghelp.h

NumReqs

The number of elements specified in the arrays specified in the ReqKinds, ReqOffsets, and ReqSizes members. These arrays must be the same size.

ReqKinds

An array of information types to be requested. Each element is one of the enumeration values in the IMAGEHLP_SYMBOL_TYPE_INFO enumeration type.

ReqOffsets

An array of offsets that specify where to store the data for each request within each element of Buffer array.

ReqSizes

The size of each data request, in bytes. The required sizes are described in IMAGEHLP_SYMBOL_TYPE_INFO.

ReqStride

The number of bytes for each element in the Buffer array.

BufferSize

The size of the Buffer array, in bytes.

Buffer

An array of records used for storing query results. Each record is separated by ReqStride bytes. Each type for which data is to be retrieved requires one record in the array. Within each record, there are NumReqs pieces of data stored as the result of individual queries. The data is stored within the record according to the offsets specified in ReqOffsets. The format of the data depends on the value of the ReqKinds member in use.

EntriesMatched

The number of type entries that match the filter.

EntriesFilled

The number of elements in the Buffer array that received results.

TagsFound

A bitmask indicating all tag bits encountered during the search operation.

AllReqsValid

A bitmask indicate the bit-wise AND of all ReqsValid fields.

NumReqsValid

The size of ReqsValid, in elements.

ReqsValid

A bitmask indexed by Buffer element index that indicates which request data is valid. This member can be NULL.

Requirements

Redistributable	DbgHelp.dll 6.3 or later
