19 getsockcreatecon retrieves the context used for creating a new labeled
20 network socket. This returned context should be freed with freecon if
21 non-NULL. getsockcreatecon sets *con to NULL if no sockcreate context
22 has been explicitly set by the program (i.e. using the default policy
23 behavior).
24
25 setsockcreatecon sets the context used for creating a new labeled net‐
26 work sockets NULL can be passed to setsockcreatecon to reset to the
27 default policy behavior. The sockcreate context is automatically reset
28 after the next execve, so a program doesn't need to explicitly sanitize
29 it upon startup.
30
31 setsockcreatecon can be applied prior to library functions that inter‐
32 nally perform an file creation, in order to set an file context on the
33 objects.

35
36 Note: Signal handlers that perform an setsockcreate must take care to
37 save, reset, and restore the sockcreate context to avoid unexpected
38 behavior.

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