current_pos()

uint64_t llvm::impl::RAIINewLineStream::current_pos ( ) const

inlinefinalvirtual

Return the current position within the stream, not counting the bytes currently in the buffer.

Implements llvm::raw_ostream.

Definition at line 300 of file DebugLog.h.

write_impl()

void llvm::impl::RAIINewLineStream::write_impl ( const char * Ptr, size_t Size )

inlinefinalvirtual

The is the piece of the class that is implemented by subclasses.

This writes the Size bytes starting at Ptr to the underlying stream.

This function is guaranteed to only be called at a point at which it is safe for the subclass to install a new buffer via SetBuffer.

Parameters

Ptr	The start of the data to be written. For buffered streams this is guaranteed to be the start of the buffer.
Size	The number of bytes to be written.

Invariant

{ Size > 0 }

Implements llvm::raw_ostream.
