Synopsis:
void *memmove(void *dest, const void *src, size_t num);
Description:
It copies num bytes from src to dest and returns dest. One advantage with memmove is that it works even if the objects overlap.
memmove function C example:
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
struct student {
char name[100];
char course[100];
int duration;
};
int main() {
struct student *from, *to;
from = (struct student *)malloc(sizeof(struct student));
to = (struct student *)malloc(sizeof(struct student));
printf("Enter the student name:");
fgets(from->name, 30, stdin);
printf("Enter the course name:");
fgets(from->course, 30, stdin);
printf("Enter the duration:");
scanf("%d", &from->duration);
to = (struct student *)memmove(to, from, sizeof(struct student));
if (to == NULL)
printf("Error\n");
else {
printf("Output:\n");
printf("Name: %s", to->name);
printf("Course: %s", to->course);
printf("Duration: %d\n", to->duration);
}
return 0;
}
#include<string.h>
#include<stdlib.h>
struct student {
char name[100];
char course[100];
int duration;
};
int main() {
struct student *from, *to;
from = (struct student *)malloc(sizeof(struct student));
to = (struct student *)malloc(sizeof(struct student));
printf("Enter the student name:");
fgets(from->name, 30, stdin);
printf("Enter the course name:");
fgets(from->course, 30, stdin);
printf("Enter the duration:");
scanf("%d", &from->duration);
to = (struct student *)memmove(to, from, sizeof(struct student));
if (to == NULL)
printf("Error\n");
else {
printf("Output:\n");
printf("Name: %s", to->name);
printf("Course: %s", to->course);
printf("Duration: %d\n", to->duration);
}
return 0;
}
Output:
jp@jp-VirtualBox:~/cpgms/chap5$ ./a.out
Enter the student name:Stuart
Enter the course name:BE
Enter the duration:4
Output:
Name: Stuart
Course: BE
Duration: 4
Enter the student name:Stuart
Enter the course name:BE
Enter the duration:4
Output:
Name: Stuart
Course: BE
Duration: 4
