## Function symbol_location_ptr

boost::dll::symbol_location_ptr

## Synopsis

    // In header: <boost/dll/runtime_symbol_info.hpp>

    template<typename T>
      boost::filesystem::path
      symbol_location_ptr(T ptr_to_symbol, boost::system::error_code & ec);
    template<typename T>
      boost::filesystem::path symbol_location_ptr(T ptr_to_symbol);

## Description

On success returns full path and name to the binary object that holds symbol pointed by ptr_to_symbol.

Examples:

    int main() {
       dll::symbol_location_ptr(std::set_terminate(0));       // returns "/some/path/libmy_terminate_handler.so"
       dll::symbol_location_ptr(::signal(SIGSEGV, SIG_DFL));  // returns "/some/path/libmy_symbol_handler.so"
    }

Parameters: |

`ec` | Variable that will be set to the result of the operation.
`ptr_to_symbol` | Pointer to symbol which location is to be determined.

Returns: | Path to the binary object that holds symbol or empty path in case error.
Throws: | std::bad_alloc in case of insufficient memory. Overload that does not accept boost::system::error_code also throws boost::system::system_error.
