Buffer Manipulation

Use these routines to work with areas of memory on a byte-by-byte basis.

Buffer-Manipulation Routines

Routine	Use	.NET Framework equivalent
_memccpy	Copy characters from one buffer to another until given character or given number of characters has been copied	System::Buffer::BlockCopy, System::String::Copy
memchr, wmemchr	Return pointer to first occurrence, within specified number of characters, of given character in buffer	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
memcmp, wmemcmp	Compare specified number of characters from two buffers	System::String::Compare, System::String::Equals
memcpy, wmemcpy, memcpy_s, wmemcpy_s	Copy specified number of characters from one buffer to another	System::Buffer::BlockCopy, System::String::Copy
_memicmp, _memicmp_l	Compare specified number of characters from two buffers without regard to case	System::String::Compare, System::String::Equals
memmove, wmemmove,memmove_s, wmemmove_s	Copy specified number of characters from one buffer to another	System::Buffer::BlockCopy
memset, wmemset	Use given character to initialize specified number of bytes in the buffer	System::Buffer::SetByte
_swab	Swap bytes of data and store them at specified location	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.

When the source and target areas overlap, only memmove is guaranteed to copy the full source properly.
