int getsockcreatecon(char **con);
int getsockcreatecon_raw(char **con);
int setsockcreatecon(char *context);
int setsockcreatecon_raw(char *context);
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(2), so a program doesn't need to explicitly sanitize 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.
getsockcreatecon_raw() and setsockcreatecon_raw() behave identically to their non-raw counterparts but do not perform context translation.
Note: Signal handlers that perform a setsockcreatecon() must take care to save, reset, and restore the sockcreate context to avoid unexpected behavior.
Note: Contexts are thread specific.
