SymGetSymFromAddr function (dbghelp.h)
Locates the symbol for the specified address.
BOOL IMAGEAPI SymGetSymFromAddr( [in] HANDLE hProcess, [in] DWORD dwAddr, [out, optional] PDWORD pdwDisplacement, [in, out] PIMAGEHLP_SYMBOL Symbol );
A handle to the process that was originally passed to the SymInitialize function.
The address for which a symbol is to 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 beginning of the symbol plus the symbol size), the symbol is found.
[out, optional] pdwDisplacement
The displacement from the beginning of the symbol, or zero.
[in, out] Symbol
A pointer to an IMAGEHLP_SYMBOL64 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 SymGetSymFromAddr64 function locates the symbol for a specified address. The modules are searched for the one the address belongs to. When the module is found, its symbol table is searched for a match. When the symbol is found, the symbol information is copied into the Symbol buffer provided by the caller. The caller must allocate the Symbol buffer properly and fill in the required parameters in the IMAGEHLP_SYMBOL64 structure before calling SymGetSymFromAddr64.
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.
This function supersedes the SymGetSymFromAddr function. For more information, see Updated Platform Support. SymGetSymFromAddr is defined as follows in Dbghelp.h.
#if !defined(_IMAGEHLP_SOURCE_) && defined(_IMAGEHLP64) #define SymGetSymFromAddr SymGetSymFromAddr64 #else BOOL IMAGEAPI SymGetSymFromAddr( __in HANDLE hProcess, __in DWORD dwAddr, __out_opt PDWORD pdwDisplacement, __inout PIMAGEHLP_SYMBOL Symbol ); #endif
