SymEnumSourceLines function

Enumerates all source lines in a module.

Syntax


BOOL WINAPI SymEnumSourceLines(
  _In_     HANDLE                  hProcess,
  _In_     ULONG64                 Base,
  _In_opt_ PCTSTR                  Obj,
  _In_opt_ PCTSTR                  File,
  _In_opt_ DWORD                   Line,
  _In_     DWORD                   Flags,
  _In_     PSYM_ENUMLINES_CALLBACK EnumLinesCallback,
  _In_opt_ PVOID                   UserContext
);

Parameters

hProcess [in]

A handle to a process. This handle must have been previously passed to the SymInitialize function.

Base [in]

The base address of the module.

Obj [in, optional]

The name of an .obj file within the module. The scope of the enumeration is limited to this file. If this parameter is NULL or an empty string, all .obj files are searched.

File [in, optional]

A wildcard expression that indicates the names of the source files to be searched. If this parameter is NULL or an empty string, all files are searched.

Line [in, optional]

The line number of a line within the module. The scope of the enumeration is limited to this line. If this parameter is 0, all lines are searched.

Flags [in]

If this parameter is ESLFLAG_FULLPATH, the function matches the full path in the File parameter.

EnumLinesCallback [in]

A SymEnumLinesProc callback function that receives the line information.

UserContext [in, optional]

A user-defined value that is passed to the callback function, or NULL. This parameter is typically used by an application to pass a pointer to a data structure that provides context for the callback function.

Return value

If the function succeeds, the return value is TRUE.

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