mi::neuraylib::IReader
A reader supports binary block reads and string-oriented line reads that zero-terminate the result.
Definition: ireader.h:27
mi::neuraylib::IReader::supports_lookahead
virtual bool supports_lookahead() const =0
Indicates whether lookahead is (in principle) supported.
mi::neuraylib::IReader::read
virtual Sint64 read(char *buffer, Sint64 size)=0
Reads a number of bytes from the stream.
mi::neuraylib::IReader::readline
virtual bool readline(char *buffer, Sint32 size)=0
Reads a line from the stream.
mi::neuraylib::IReader::lookahead
virtual Sint64 lookahead(Sint64 size, const char **buffer) const =0
Gives access to the lookahead data.
