SymGetLineFromAddr

The SymGetLineFromAddr function locates the source line for the specified address.

This function is implemented as a wrapper that calls SymGetLineFromAddr64. For more information, see New 64-bit Functions.

BOOL SymGetLineFromAddr(
  HANDLE hProcess,
  DWORD dwAddr,
  PDWORD pdwDisplacement,
  PIMAGEHLP_LINE Line
);

For SymGetLineFromAddr64, the parameter list is as follows.

BOOL SymGetLineFromAddr64(
  HANDLE hProcess,
  DWORD64 dwAddr,
  PDWORD pdwDisplacement,
  PIMAGEHLP_LINE64 Line
);

Parameters

hProcess

[in] Handle to the process that was originally passed to the SymInitialize function.

dwAddr

[in] Specifies the address for which a line should be located. It is not necessary for the address to be on a line boundary. If the address appears after the beginning of a line and before the end of the line, the line is found.

[out] The displacement from the beginning of the line, or zero.

Line

[out] Pointer to an IMAGEHLP_LINE structure.

Return Value

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