Buffer Manipulation

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

Buffer-Manipulation Routines

RoutineUse.NET Framework equivalent
_memccpyCopy characters from one buffer to another until given character or given number of characters has been copiedSystem::Buffer::BlockCopy, System::String::Copy
memchr, wmemchrReturn pointer to first occurrence, within specified number of characters, of given character in bufferNot applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
memcmp, wmemcmpCompare specified number of characters from two buffersSystem::String::Compare, System::String::Equals
memcpy, wmemcpy, memcpy_s, wmemcpy_sCopy specified number of characters from one buffer to anotherSystem::Buffer::BlockCopy, System::String::Copy
_memicmp, _memicmp_lCompare specified number of characters from two buffers without regard to caseSystem::String::Compare, System::String::Equals
memmove, wmemmove,memmove_s, wmemmove_sCopy specified number of characters from one buffer to anotherSystem::Buffer::BlockCopy
memset, wmemsetUse given character to initialize specified number of bytes in the bufferSystem::Buffer::SetByte
_swabSwap bytes of data and store them at specified locationNot 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.
