       getlabel, fgetlabel - get file sensitivity label

       cc [flags...] file... -ltsol [library...]

       #include <tsol/label.h>

       int getlabel(const char *path, m_label_t *label_p);

       int fgetlabel(int fd, m_label_t *label_p);

       The  getlabel()	function obtains the sensitivity label of the file that is named by path.
       Discretionary read, write or execute permission to the final  component	of  path  is  not
       required, but all directories in the path prefix of path must be searchable.

       The  fgetlabel()  function  obtains  the  label of an open file that is referred to by the
       argument descriptor, such as would be obtained by an open(2) call.

       The label_p argument is a pointer to an opaque label structure. The caller  must  allocate
       space for label_p by using m_label_alloc(3TSOL).

       Upon  successful completion, getlabel() and fgetlabel() return 0. Otherwise they return -1
       and set errno to indicate the error.

       The getlabel() function will fail if:

       EACCES	       Search permission is denied for a component of the path prefix of path. To
		       override   this	 restriction,	the   calling	process  can  assert  the
		       PRIV_FILE_DAC_SEARCH privilege.

       EFAULT	       label_p or path points to an invalid address.

       EIO	       An I/O error occurred while reading from or writing to the file system.

       ELOOP	       Too many symbolic links were encountered in translating path.

       ENAMETOOLONG    The length of the path argument exceeds PATH_MAX, or a pathname	component
		       is  longer  than  NAME_MAX  while  _POSIX_NO_TRUNC is in effect (see path-

       ENOENT	       The file referred to by path does not exist.

       ENOTDIR	       A component of the path prefix of path is not a directory.

       The fgetlabel() function will fail if:

       EBADF	 The fd argument is not a valid open file descriptor.

       EFAULT	 The label_p argument points to an invalid address.

       EIO	 An I/O error occurred while reading from or writing to the file system.
