d_path — return the path of a dentry
char * d_path ( | const struct path * path, |
| char * buf, | |
int buflen); |
Convert a dentry into an ASCII path name. If the entry has been deleted the string “ (deleted)” is appended. Note that this is ambiguous.
Returns a pointer into the buffer or an error code if the path was too long. Note: Callers should use the returned pointer, not the passed in buffer, to use the name! The implementation often starts at an offset into the buffer, and may leave 0 bytes at the start.
“buflen” should be positive.
