memmove
Description:
Include:
Prototype:
Arguments:
Return Value:
Remarks:
Example:
Copies n characters of the source buffer into the destination buffer,
even if the regions overlap.
<string.h>
void *memmove(void *s1, const void *s2, size_t n);
s1
s2
n
Returns a pointer to the destination buffer
If the buffers overlap, the effect is as if the characters are read first from
s2 then written to s1 so the buffer is not corrupted.
#include <string.h> /* for memmove */
#include <stdio.h>
int main(void)
{
}
Output:
buf1 : When time marches on
buf2 : Where is the time?
buf3 : Why?
buf1 after memmove of 6 chars of buf2:
buf1 after memmove of 5 chars of buf3:
char buf1[50] = "When time marches on";
char buf2[50] = "Where is the time?";
char buf3[50] = "Why?";
printf("buf1 : %s\n", buf1);
printf("buf2 : %s\n", buf2);
printf("buf3 : %s\n\n", buf3);
memmove(buf1, buf2, 6);
printf("buf1 after memmove of 6 chars of "
printf("\n");
memmove(buf1, buf3, 5);
printf("buf1 after memmove of 5 chars of "
Where ime marches on
Why?
"buf2: \n\t%s\n", buf1);
"buf3: \n\t%s\n", buf1);
buffer to copy characters to (destination)
buffer to copy characters from (source)
