Library FunctionsMEMCPYSynopsis#include void * memcpy (void * d, const void * s, size_t n)DescriptionThe memcpy() function copies n bytes of memory starting from the location pointed to by s tothe block of memory pointed to by d. The result of copying overlapping blocks is undefined. Thememcpy() function differs from strcpy() in that it copies a specified number of bytes, rather than allbytes up to a null terminator.Example#include #include voidmain (void){char buf[80];}memset(buf, 0, sizeof buf);memcpy(buf, "a partial string", 10);printf("buf = ’%s’\n", buf);See Alsostrncpy(), strncmp(), strchr(), memset()Return ValueThe memcpy() routine returns its first argument.169
