Hi...
Does anyone know how to implement a function that returns a const char* for use in this situation:
The part that is causing problems is that I don't want to use malloc in c_str() since that would produce a memory leak in such a case.Code:class foo { protected: int i_size; char* c_data; // not necesarily null terminated ... public: const char* c_str() { // - how to implement ? // - should add a null terminator to c_data // - not neccesary: possybitlity of aditional manipulation of i_data // ( concat with another string ) // - only the returned string should contain the changes - i_data should // not be changed in the process } ... }; void bar( const char* c ) { // operations on the null terminated c string } in main: foo test( "abc" ); bar( test.c_str() ); // this part uses c_str() function to convert data to the bar function // input type ( const char* )
Any ideas anyone?
Thanks, Domen.
