Locates a source line for the specified module, file name, and line number.
BOOL IMAGEAPI SymGetLineFromName( HANDLE hProcess, PCSTR ModuleName, PCSTR FileName, DWORD dwLineNumber, PLONG plDisplacement, PIMAGEHLP_LINE Line );
A handle to the process that was originally passed to the SymInitialize function.
The name of the module in which a line is to be located.
The name of the file in which a line is to be located. If the application has more than one source file with this name, be sure to specify a full path.
The line number to be located.
The displacement in bytes from the beginning of the line, or zero.
A pointer to an IMAGEHLP_LINE64 structure.
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.
The caller must allocate the Line buffer properly and fill in the required members of the IMAGEHLP_LINE64 structure before calling SymGetLineFromName64.
This function returns a pointer to a buffer that may be reused by another function. Therefore, be sure to copy the data returned to another buffer immediately.
All DbgHelp functions, such as this one, are single threaded. Therefore, calls from more than one thread to this function will likely result in unexpected behavior or memory corruption. To avoid this, you must synchronize all concurrent calls from more than one thread to this function.
To call the Unicode version of this function, define DBGHELP_TRANSLATE_TCHAR. SymGetLineFromNameW64 is defined as follows in Dbghelp.h.
BOOL IMAGEAPI SymGetLineFromNameW64( __in HANDLE hProcess, __in_opt PCWSTR ModuleName, __in_opt PCWSTR FileName, __in DWORD dwLineNumber, __out PLONG plDisplacement, __inout PIMAGEHLP_LINEW64 Line ); #ifdef DBGHELP_TRANSLATE_TCHAR #define SymGetLineFromName64 SymGetLineFromNameW64 #endif
This function supersedes the SymGetLineFromName function. For more information, see Updated Platform Support. SymGetLineFromName is defined as follows in Dbghelp.h.
#if !defined(_IMAGEHLP_SOURCE_) && defined(_IMAGEHLP64) #define SymGetLineFromName SymGetLineFromName64 #else BOOL IMAGEAPI SymGetLineFromName( __in HANDLE hProcess, __in_opt PCSTR ModuleName, __in_opt PCSTR FileName, __in DWORD dwLineNumber, __out PLONG plDisplacement, __inout PIMAGEHLP_LINE Line ); #endif
