oefpos_t read(char *buffer, oefpos_t len) oefpos_t read(signed char *buffer, oefpos_t len) oefpos_t read(unsigned char *buffer, oefpos_t len) oefpos_t read(std::string &buffer, oefpos_t len)
Reads the next len
number of bytes off of the stream, stores them in the
specified buffer
and returns the number of bytes actually read. It is
the user's responsibility when using any of the three char *
versions to
make sure that the specified buffer
has been properly allocated and has
enough room to store len
bytes. This function does not add a NULL
terminator to the end of the buffer.
