Detailed Description

Represents a file stream supporting synchronous and asynchronous read and write operations. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.

Constructor & Destructor Documentation

◆ FileStream()

System::IO::FileStream::FileStream	(	const String &	path,

◆ WriteByte()

void System::IO::FileStream::WriteByte ( uint8_t value )

overridevirtual

Writes the specified unsigned 8-bit integer value to the stream.

Parameters

value The value to write

Reimplemented from System::IO::Stream.
