getsockcreatecon(3)        SELinux API documentation       getsockcreatecon(3)

NAME
       getsockcreatecon,  setsockcreatecon  -  get or set the SELinux security
       context used for creating a new labeled sockets
SYNOPSIS
       #include <selinux/selinux.h>
       int getsockcreatecon(char **con);
       int getsockcreatecon_raw(char **con);
       int setsockcreatecon(char * context);
       int setsockcreatecon_raw(char * context);
DESCRIPTION
       getsockcreatecon() retrieves  the  context  used  for  creating  a  new
       labeled  network  socket.   This  returned context should be freed with
       freecon(3) 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(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.

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