SymFromAddr function (dbghelp.h)
Retrieves symbol information for the specified address.
BOOL IMAGEAPI SymFromAddr( [in] HANDLE hProcess, [in] DWORD64 Address, [out, optional] PDWORD64 Displacement, [in, out] PSYMBOL_INFO Symbol );
A handle to a process. This handle must have been previously passed to the SymInitialize function.
The address for which a symbol should be located. The address does not have to be on a symbol boundary. If the address comes after the beginning of a symbol and before the end of the symbol, the symbol is found.
[out, optional] Displacement
The displacement from the beginning of the symbol, or zero.
[in, out] Symbol
A pointer to a SYMBOL_INFO structure that provides information about the symbol. The symbol name is variable in length; therefore this buffer must be large enough to hold the name stored at the end of the SYMBOL_INFO structure. Be sure to set the MaxNameLen member to the number of bytes reserved for the name.
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.
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.
