NAME

     system firewall rules list management

LIBRARY

     File System Firewall Interface Library (libugidfw, -lugidfw)

SYNOPSIS

     #include <ugidfw.h>

     int
     bsde_add_rule(int *rulenum, struct mac_bsdextended_rule *rule,
	 size_t buflen, char *errstr);

     int
     bsde_get_rule(int rulenum, struct mac_bsdextended_rule *rule,
	 size_t errlen, char *errstr);

     int
     bsde_set_rule(int rulenum, struct mac_bsdextended_rule *rule,
	 size_t errlen, char *errstr);

     int
     bsde_delete_rule(int rulenum, size_t errlen, char *errstr);

DESCRIPTION

     The bsde_add_rule() function fills the next available rule (in struct
     mac_bsdextended_rule form, either from bsde_get_rule() or
     bsde_parse_rule(3)).  If an error occurs, *errstr is filled with the
     error string (up to errlen characters, including the terminating NUL).
     If successful and rulenum is non-NULL, the rule number used will be
     returned in *rulenum.

     The bsde_get_rule() function fills in *rule with the rule numbered
     rulenum.  If an error occurs, *errstr is filled in with the error string
     (up to errlen characters, including the terminating NUL).

     The bsde_set_rule() function fills the slot numbered rulenum with the
     specified rule (in struct mac_bsdextended_rule form, either from
     bsde_get_rule() or bsde_parse_rule(3)).  If an error occurs, *errstr is
     filled with the error string (up to errlen characters, including the ter-
     minating NUL).

     The bsde_delete_rule() function deletes the rule numbered rulenum.  If an
     error occurs, *errstr is filled with the error string (up to errlen char-
     acters, including the terminating NUL).

RETURN VALUES

     The bsde_get_rule(), bsde_set_rule(), and bsde_delete_rule() functions
     return 0 if successful; otherwise the value -1 is returned and the value
     of *errstr is filled in as documented in DESCRIPTION.
