stdmemmove
Stdmemmove is a function in the standard memory manipulation library used by several programming environments to move a sequence of bytes from a source region to a destination region, allowing the source and destination to overlap. It is functionally equivalent to memmove in C, and is designed to be safer than memcpy for overlapping regions.
Prototype: void *stdmemmove(void *dest, const void *src, size_t n); It returns a pointer to dest. The operation
Behavior with overlap: When the source and destination buffers overlap, stdmemmove ensures the bytes are copied
Performance and implementation: The function may be implemented using temporary buffering or by directional copying; performance
Safety and usage: Pointers must be valid for reading or writing n bytes; if not, the behavior
