NAME
       getsockcreatecon, setsockcreatecon - get or set the SELinux security context used for creating a new labeled sockets.

SYNOPSIS
       #include <selinux/selinux.h>

       int getsockcreatecon(security_context_t *con);

       int setsockcreatecon(security_context_t context);

DESCRIPTION
       getsockcreatecon  retrieves the context used for creating a new labeled network socket.	This returned context should be freed with freecon
       if non-NULL.  getsockcreatecon sets *con to NULL if no sockcreate context has been explicitly set by the program (i.e.  using  the  default
       policy behavior).

       setsockcreatecon  sets  the  context used for creating a new labeled network sockets NULL can be passed to setsockcreatecon to reset to the
       default policy behavior.  The sockcreate context is automatically reset after the next execve, so a program doesn't need to explicitly san-
       itize it upon startup.

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

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

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