This may be trivial, but I'm new to C++
and an getting confused here.
I have the method:
bool load_database_file( const std::string& filename, std::string& contents ) {
std::ifstream is (filename, std::ifstream::binary);
if (is) {
// get length of file:
is.seekg (0, is.end);
int length = (int)is.tellg();
is.seekg (0, is.beg);
char * buffer = new char [length];
std::cout << "Reading " << length << " characters... ";
// read data as a block:
is.read (buffer, length);
if (is)
std::cout << "all characters read successfully.";
else
std::cout << "error: only " << is.gcount() << " could be read";
is.close();
// ...buffer contains the entire file...
std::string str(buffer);
contents = str;
delete[] buffer;
}
return true ;
}
where I would like to read a file and assign it's contents to contents
so that it can be read by the calling function.
My issue is that after this function is run, I see that only the first character of buffer
was copied to contents
.
How can I copy/convert the entire contents of buffer
(a char *
) to contents
(a std::string
).
