SymGetFileLineOffsets64 function

Locates line information for the specified module and file name.

Syntax


ULONG WINAPI SymGetFileLineOffsets64(
  _In_      HANDLE hProcess,
  _In_opt_  PCSTR ModuleName,
  _In_      PCSTR FileName,
  _Out_     PDWORD64 Buffer,
  _In_      ULONG BufferLines
);

Parameters

hProcess [in]

A handle to the process that was originally passed to the SymInitialize function.

ModuleName [in, optional]

The name of the module in which lines are to be located. If this parameter is NULL, the function searches all modules.

FileName [in]

The name of the file in which lines are to be located.

Buffer [out]

An array of offsets for each line. The offset for the line n is stored in element n-1. Array elements for lines that do not have line information are left unchanged.

BufferLines [in]

The size of the Buffer array, in elements.

Return value

If the function succeeds, the return value is the highest line number found. This value is zero if no line information was found.

If the function fails, the return value is LINE_ERROR. To retrieve extended error information, call GetLastError.
