getlabel(2)							   System Calls 						       getlabel(2)

NAME
       getlabel, fgetlabel - get file sensitivity label

SYNOPSIS
       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);

DESCRIPTION
       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).

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

ERRORS
       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 pathconf(2)).

       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.
