getfscreatecon(3) SELinux API documentation getfscreatecon(3)
getfscreatecon, setfscreatecon - get or set the SELinux security
context used for creating a new file system object
#include <selinux/selinux.h>
int getfscreatecon(char **con);
int getfscreatecon_raw(char **con);
int setfscreatecon(const char *context);
int setfscreatecon_raw(const char *context);
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
translation.
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.
On error -1 is returned. On success 0 is returned.
