peek()

char fc::buffered_istream::peek ( ) const

virtual

This method may block until at least 1 character is available.

Definition at line 112 of file buffered_iostream.cpp.

readsome() [1/2]

size_t fc::buffered_istream::readsome ( char *  buf, size_t  len  )

virtual

read at least 1 byte or throw, if no data is available this method should block cooperatively until data is available or fc::eof_exception is thrown.

Precondition

len > 0

buf != nullptr

Exceptions

fc::eof

if at least 1 byte cannot be read

Implements fc::istream.

readsome() [2/2]

size_t fc::buffered_istream::readsome ( const std::shared_ptr< char > &  buf, size_t  len, size_t  offset  )

virtual

Implements fc::istream.
