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.
