C# Class GSF.IO.Unmanaged.Memory

This class is used to allocate and free unmanaged memory. To release memory allocated throught this class, call the Dispose method of the return value.

.NET does not respond well when managing tens of GBs of ram. If a very large buffer pool must be created, it would be good to allocate that buffer pool in unmanaged memory.

Public Methods

Method	Description
Clear ( IntPtr pointer, int length ) : void	Sets the data in this buffer to all zeroes
Clear ( byte pointer, int length ) : void	Sets the data in this buffer to all zeroes
Copy ( IntPtr src, IntPtr dest, int count ) : void	Does a safe copy of data from one location to another. A safe copy allows for the source and destination to overlap.
Copy ( byte src, byte dest, int count ) : void	Does a safe copy of data from one location to another. A safe copy allows for the source and destination to overlap.
Dispose ( ) : void	Releases all the resources used by the Memory object.
Memory ( int requestedSize ) : System	Allocates unmanaged memory. The block is uninitialized.
Release ( ) : void	Releases the allocated memory back to the OS. Same thing as calling Dispose().

Method Details

Clear() public static method

Sets the data in this buffer to all zeroes

public static Clear ( IntPtr pointer, int length ) : void
pointer	System.IntPtr	the starting position.
length	int	the number of bytes to clear.
return	void

Clear() public static method

Sets the data in this buffer to all zeroes

public static Clear ( byte pointer, int length ) : void
pointer	byte	the starting position.
length	int	the number of bytes to clear.
return	void

Copy() public static method

Does a safe copy of data from one location to another. A safe copy allows for the source and destination to overlap.

public static Copy ( IntPtr src, IntPtr dest, int count ) : void
src	System.IntPtr
dest	System.IntPtr
count	int
return	void

Copy() public static method

Does a safe copy of data from one location to another. A safe copy allows for the source and destination to overlap.

public static Copy ( byte src, byte dest, int count ) : void
src	byte
dest	byte
count	int
return	void

Dispose() public method

Releases all the resources used by the Memory object.

public Dispose ( ) : void
return	void

Memory() public method

Allocates unmanaged memory. The block is uninitialized.

public Memory ( int requestedSize ) : System
requestedSize	int	The desired number of bytes to allocate. /// Be sure to check the actual size in the return class.
return	System

Release() public method

Releases the allocated memory back to the OS. Same thing as calling Dispose().

public Release ( ) : void
return	void
