<H2>DESCRIPTION</H2>
|
|
|
|
<B>getfilecon</B>()
|
|
|
|
retrieves the context associated with the given path in the file system, the
|
|
length of the context is returned.
|
|
<P>
|
|
<B>lgetfilecon</B>()
|
|
|
|
is identical to
|
|
<B>getfilecon</B>(),
|
|
|
|
except in the case of a symbolic link, where the
|
|
link itself is interrogated, not the file that it refers to.
|
|
<P>
|
|
<B>fgetfilecon</B>()
|
|
|
|
is identical to
|
|
<B>getfilecon</B>(),
|
|
|
|
only the open file pointed to by filedes (as returned by
|
|
<B><A HREF="/cgi-bin/man/man2html?2+open">open</A></B>(2))
|
|
|
|
is interrogated in place of path.
|
|
<P>
|
|
<B>getfilecon_raw</B>(),
|
|
|
|
<B>lgetfilecon_raw</B>()
|
|
|
|
and
|
|
<B>fgetfilecon_raw</B>()
|
|
|
|
behave identically to their non-raw counterparts but do not perform context
|
|
translation.
|
|
<P>
|
|
The returned context should be freed with
|
|
<B><A HREF="/cgi-bin/man/man2html?3+freecon">freecon</A></B>(3)
|
|
|
|
if non-NULL.

|
|
<H2>RETURN VALUE</H2>
|
|
|
|
On success, a positive number is returned indicating the size of the
|
|
extended attribute value. On failure, -1 is returned and
|
|
<I>errno</I>
|
|
|
|
is set appropriately.
|
|
<P>
|
|
If the context does not exist, or the process has no access to
|
|
this attribute,
|
|
<I>errno</I>
|
|
|
|
is set to
|
|
<B>ENODATA</B>.
|
|
|
|
<P>
|
|
If extended attributes are not supported by the filesystem, or are
|
|
disabled,
|
|
<I>errno</I>
|
|
|
|
is set to
|
|
<B>ENOTSUP</B>.
|
|
|
|
<P>
|
|
The errors documented for the
|
|
<B><A HREF="/cgi-bin/man/man2html?2+stat">stat</A></B>(2)
|
|
|
|
system call are also applicable here.
