IDebugSymbols3::GetSourceFileLineOffsets method (dbgeng.h)
The GetSourceFileLineOffsets method maps each line in a source file to a location in the target's memory.
Syntax
HRESULT GetSourceFileLineOffsets(
[in] PCSTR File,
[out, optional] PULONG64 Buffer,
[in] ULONG BufferLines,
[out, optional] PULONG FileLines
);
Parameters
[in] File
Specifies the name of the file whose lines will be turned into locations in the target's memory. The symbols for each module in the target are queried for this file. If the file is not located, the path is dropped and the symbols are queried again.
[out, optional] Buffer
Receives the locations in the target's memory that correspond to the lines of the source code. The first entry returned to this array corresponds to the first line of the file, so that Buffer[i] contains the location for line i+1. If no symbol information is available for a line, the corresponding entry in Buffer is set to DEBUG_INVALID_OFFSET. If Buffer is NULL, this information is not returned.
[in] BufferLines
Specifies the number of PULONG64 objects that the Buffer array can hold.
[out, optional] FileLines
Receives the number of lines in the source file specified by File.
Return value
This method can also return error values. See Return Values for more details.
| Return code | Description |
|---|---|
|
The method was successful. |
|
The method was successful. However, the number of lines in the source file exceeded the number of entries in the Buffer array and some of the results were discarded. |
Remarks
For more information about using the source path, see Using Source Files.
