int vn_symlink (vp, linkname, target, crp) struct vnode *vp; char *linkname; char *target; struct ucred *crp;
| vp | Points to the virtual node (v-node) of the parent directory where the link is created. |
| linkname | Points to the name of the new symbolic link. The logical file system guarantees that the new link does not already exit. |
| target | Points to the name of the object to which the symbolic link points. This name need not be a fully qualified path name or even an existing object. |
| crp | Points to the cred structure. This structure contains data that the file system can use to validate access permission. |
The vn_symlink entry point is called by the logical file system to create a symbolic link. The path name specified by the linkname parameter is the name of the new symbolic link. This symbolic link points to the object named by the target parameter.
The vn_symlink entry point can be called from the process environment only.
| 0 | Indicates success. |
Nonzero return values are returned from the /usr/include/sys/errno.h file to indicate failure.
