NAME         top

       getfscreatecon, setfscreatecon - get or set the SELinux security
       context used for creating a new file system object

SYNOPSIS         top

       #include <selinux/selinux.h>

       int getfscreatecon(char **con);

       int getfscreatecon_raw(char **con);

       int setfscreatecon(char *context);

       int setfscreatecon_raw(char *context);

DESCRIPTION         top

       getfscreatecon() retrieves the context used for creating a new
       file system object.  This returned context should be freed with
       freecon(3) if non-NULL.  getfscreatecon() sets *con to NULL if no
       fscreate context has been explicitly set by the program (i.e.
       using the default policy behavior).

       setfscreatecon() sets the context used for creating a new file
       system object.  NULL can be passed to setfscreatecon() to reset
       to the default policy behavior.  The fscreate context is
       automatically reset after the next execve(2), so a program
       doesn't need to explicitly sanitize it upon startup.

       setfscreatecon() can be applied prior to library functions that
       internally perform an file creation, in order to set an file
       context on the objects.

       getfscreatecon_raw() and setfscreatecon_raw() behave identically
       to their non-raw counterparts but do not perform context

       Note: Signal handlers that perform a setfscreatecon() must take
       care to save, reset, and restore the fscreate context to avoid
       unexpected behavior.

       Note: Contexts are thread specific.

RETURN VALUE         top

       On error -1 is returned.  On success 0 is returned.
