# Difference between hardlinks and symlinks
|
||
|
|
|
||
|
|
### Hardlinks
|
||
|
|
- implementation of `ln`
|
||
|
|
- kinda like shortcut, but a shortcut to a physical memory location!!!!
|
||
|
|
|
||
|
|
```c
|
||
|
|
/*
|
||
|
|
* creates new file, that points to same memory location as provided file
|
||
|
|
* - if one of the files is edited, then both files change
|
||
|
|
* - if one of the files gets deleted, then just inode of that file, that points to that location is deleted
|
||
|
|
* other file stays undeleted, with same content
|
||
|
|
*/
|
||
|
|
int hardlink(char *dest, char *name) {
|
||
|
|
if(link(dest, name) < 0)
|
||
|
|
return errno;
|
||
|
|
return 0;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Softlinks
|
||
|
|
- implementation of `ln -s`
|
||
|
|
- it works like a shortcut to original file
|
||
|
|
|
||
|
|
```c
|
||
|
|
/*
|
||
|
|
* creates a new file, that points to provided file
|
||
|
|
* - if one of the files is edited, then both files change
|
||
|
|
* - if original file gets deleted, then also disk contents gets deleted, and link is broken
|
||
|
|
*/
|
||
|
|
int softlink(char *dest, char *name) {
|
||
|
|
if(symlink(dest, name) < 0)
|
||
|
|
return errno;
|
||
|
|
return 0;
|
||
|
|
}
|
||
|
|
```
