i need to read a whole file to a string and return it, but i can't imagine how to do this without having to read
the whole file to a char* buffer first and assigning (copying) to a string later. Is there another way around ?
the code (without error checking):
string file_read( string filename )
unsigned filesize = file_size( filename ); // suppose file_size() defined
char *buf = new char[ filesize ];
int fd = open( filename, O_RDONLY );
read( fd, buf, filesize );
string ret( buf, filesize );
is there a way round without having to allocate and copy buf ?
thanks for any help
