Syntax

  #include <string.h> 
   
  void *memcpy (
     void         *dst,   
     const void   *src,   
     size_t        length);

Parameters

dst

(OUT) Points to a buffer into which to copy the characters.

src

(IN) Points to a buffer containing the characters to be copied.

length

(IN) Specifies the number of characters to copy.

Return Values

Remarks

The memcpy function copies length characters from the buffer pointed to by src into the buffer pointed to by dst. Copying of overlapping objects has undefined results. See memmove to copy objects that overlap.
