The majority of prototypes don't put a space between the "*" and the parameter name. i.e. this style is incorrect: char * foo; Instead, we want: char *foo; Fix a bunch of references that use this uncommon style. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

.SH "DESCRIPTION"
|
|
.BR getsockcreatecon ()
|
|
retrieves the context used for creating a new labeled network socket.
|
|
This returned context should be freed with
|
|
.BR freecon (3)
|
|
if non-NULL.
|
|
.BR getsockcreatecon ()
|
|
sets *con to NULL if no sockcreate context has been explicitly
|
|
set by the program (i.e. using the default policy behavior).
|
|
|
|
.BR setsockcreatecon ()
|
|
sets the context used for creating a new labeled network sockets
|
|
NULL can be passed to
|
|
.BR setsockcreatecon ()
|
|
to reset to the default policy behavior.
|
|
The sockcreate context is automatically reset after the next
|
|
.BR execve (2),
|
|
so a program doesn't need to explicitly sanitize it upon startup.
|
|
|
|
.BR setsockcreatecon ()
|
|
can be applied prior to library
|
|
functions that internally perform an file creation,
|
|
in order to set an file context on the objects.
|
|
|
|
.BR getsockcreatecon_raw ()
|
|
and
|
|
.BR setsockcreatecon_raw ()
|
|
behave identically to their non-raw counterparts but do not perform context
|
|
translation.
|
|
|
|
.B Note:
|
|
Signal handlers that perform a
|
|
.BR setsockcreatecon ()
|
|
must take care to
|
|
save, reset, and restore the sockcreate context to avoid unexpected behavior.

On success 0 is returned.
