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.
