d_path — return the path of a dentry


char * d_path (const struct path * path,
 char * buf,
 int buflen);


const struct path * path

path to report

char * buf

buffer to return value in

int buflen

buffer length


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.
