Retrieves a list of paths that are searched for symbols as well as the results of searching each path.

Syntax

HRESULT GetSymbolInfo(
    SYMBOL_SEARCH_INFO_FIELDS  dwFields,
    MODULE_SYMBOL_SEARCH_INFO* pInfo
);

int GetSymbolInfo(
    enum_SYMBOL_SEARCH_INFO_FIELDS dwFields,
    MODULE_SYMBOL_SEARCH_INFO[]    pinfo
);

Parameters

dwFields
[in] A combination of flags from the SYMBOL_SEARCH_INFO_FIELDS enumeration specifying which fields of pInfo are to be filled in.

pInfo
[out] A MODULE_SYMBOL_SEARCH_INFO structure whose members are to be filled in with the specified information. If this is a null value, this method returns E_INVALIDARG.

Return Value

If the method succeeds, it returns S_OK; otherwise, it returns an error code.

Note

The returned string (in the MODULE_SYMBOL_SEARCH_INFO structure) could be empty even if S_OK is returned. In this case, there was no search information to return.

Remarks

If the bstrVerboseSearchInfo field of the MODULE_SYMBOL_SEARCH_INFO structure is not empty, then it contains a list of paths searched and the results of that search. The list is formatted with a path, followed by an ellipsis ("..."), followed by the result. If there is more than one path result pair, then each pair is separated by a "\r\n" (carriage-return/linefeed) pair. The pattern looks like this:

<path>...<result>\r\n<path>...<result>\r\n<path>...<result>

Note that the last entry does not have a \r\n sequence.

Example

In this example, this method returns three paths with three different search results. Each line is terminated with a carriage-return/linefeed pair. The example output just prints the search results as a single string.

Note

A status result is everything immediately following the "..." up to the end of the line.
