NAME        top

       setfilecon, fsetfilecon, lsetfilecon - set SELinux security       context of a file

SYNOPSIS        top

#include <selinux/selinux.h>int setfilecon(const char *path, const char *con);int setfilecon_raw(const char *path, const char *con);int lsetfilecon(const char *path, const char *con);int lsetfilecon_raw(const char *path, const char *con);int fsetfilecon(intfd, const char *con);int fsetfilecon_raw(intfd, const char *con);

DESCRIPTION        top

setfilecon() sets the security context of the file system object.lsetfilecon() is identical to setfilecon, except in the case of a       symbolic link, where the link itself has it's context set, not the       file that it refers to.fsetfilecon() is identical to setfilecon, only the open file       pointed to by filedes (as returned byopen(2)) has it's context       set in place of path.  Since libselinux 3.4 a file opened viaO_PATH is supported.setfilecon_raw(),lsetfilecon_raw(), andfsetfilecon_raw() behave       identically to their non-raw counterparts but do not perform       context translation.

RETURN VALUE        top

       On success, zero is returned. On failure, -1 is returned anderrno       is set appropriately.

ERRORS        top

       If there is insufficient space remaining to store the extended       attribute,errno is set to eitherENOSPC, orEDQUOTif quota       enforcement was the cause.       If extended attributes are not supported by the filesystem, or are       disabled,errno is set toENOTSUP.       The errors documented for thestat(2) system call are also       applicable here.
