Syntax
#include <mem.h>
int memcmp (void *
buf1 , const void * buf2 , unsigned long len );
Example
#include <mem.h>
unsigned array1[40], array2[40];
void f(void)
{
// See if array1 matches array2
if (memcmp(array1, array2, sizeof(array1)) != 0) {
// The contents of the two areas does not match
}
}
memcpy( ) Built-in Function
The memcpy( ) built-in function copies a block of len bytes from src to dest . It
does not return any value. This function cannot be used to copy overlapping
areas of memory, or to write into EEPROM or flash memory. The memcpy( )
function can also be used to copy to and from the data fields of the msg_in,
resp_in, msg_out, and resp_out objects.
The memcpy( ) function as implemented here does not conform to the ANSI C
definition, because it does not return a pointer to the destination array. See
ansi_memcpy( ) for a conforming implementation. See also ansi_memset( ),
eeprom_memcpy( ), memccpy( ), memchr( ), memcmp( ), and memset( ).
Syntax
void memcpy (void * dest , void * src , unsigned long len );
Example
void f(void)
{
memcpy(msg_out.data, "Hello World", 11);
}
memset( ) Built-in Function
The memset( ) built-in function sets the first len bytes of the block pointed to by p
to the character
c . It does not return any value. This function cannot be used to
write into EEPROM or flash memory.
The memset( ) function as implemented here does not conform to the ANSI C
definition, because it does not return a pointer to the array. See ansi_memset( )
for a conforming implementation. See also ansi_memcpy( ), eeprom_memcpy( ),
memccpy( ), memchr( ), memcmp( ), and memcpy( ).
