NAME

6       getfscreatecon,  setfscreatecon  - get or set the SELinux security con‐
7       text used for creating a new file system object
8

SYNOPSIS

10       #include <selinux/selinux.h>
11
12       int getfscreatecon(char **con);
13
14       int getfscreatecon_raw(char **con);
15
16       int setfscreatecon(char * context);
17
18       int setfscreatecon_raw(char * context);

DESCRIPTION

21       getfscreatecon() retrieves the context used for  creating  a  new  file
22       system  object.   This returned context should be freed with freecon(3)
23       if non-NULL.  getfscreatecon() sets *con to NULL if no fscreate context
24       has  been  explicitly set by the program (i.e. using the default policy
25       behavior).
26
27       setfscreatecon() sets the context used for creating a new  file  system
28       object.  NULL can be passed to setfscreatecon() to reset to the default
29       policy behavior.  The fscreate context is automatically reset after the
30       next  execve(2),  so  a  program doesn't need to explicitly sanitize it
31       upon startup.
32
33       setfscreatecon() can be applied prior to library functions that  inter‐
34       nally  perform an file creation, in order to set an file context on the
35       objects.
36
37       getfscreatecon_raw() and  setfscreatecon_raw()  behave  identically  to
38       their non-raw counterparts but do not perform context translation.
39
40       Note: Signal handlers that perform a setfscreatecon() must take care to
41       save, reset, and restore  the  fscreate  context  to  avoid  unexpected
42       behavior.
43
44       Note: Contexts are thread specific.

RETURN VALUE

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