Members
m_ExtMajorVersion
The major version number of the extension library. This should be set by the Initialize method. If it is not set, it defaults to 1.m_ExtMinorVersion
The minor version number of the extension library. This should be set by the Initialize method. If it is not set, it defaults to 0 (zero).m_ExtInitFlags
The DbgEng extension initialization flags for DebugExtensionInitialize.m_KnownStructs
An array of ExtKnownStruct structures that the extension library is capable of formatting for output. This member should be set by the Initialize method and should not be changed once this method returns.If m_KnownStructs is not NULL, the TypeName member of the last ExtKnownStruct structure in the array must be NULL.
When formatting a target's structure for output, if the name of the structure's type matches the TypeName member of one of the ExtKnownStruct structures in this array, the callback function specified in the Method member is called to perform the formatting.
m_ProvidedValues
An array of ExtProvidedValue structures listing the pseudo registers that the extension library can provide values for. This member should be set by the Initialize method and should not be changed once this method returns.If m_ProvidedValues is not NULL, the ValueName member of the last ExtProvidedValue structure in the array must be NULL.
When evaluating a pseudo register, if the name of the pseudo register matches the ValueName member of one of the ExtProvidedValue structures in this array, the callback function specified in the Method member is called to evaluate the pseudo register.
