const char* ast_security_event_get_name ( const enum ast_security_event_type event_type )

Get the name of a security event sub-type.

Parameters:

[in] event_type security event sub-type

Return values:

NULL	if event_type is invalid
non-NULL	the name of the security event type

}

struct ast_security_event_ie_type* ast_security_event_get_optional_ies ( const enum ast_security_event_type event_type ) [read]

Get the list of optional IEs for a given security event sub-type.

Parameters:

[in] event_type security event sub-type

Return values:

NULL	invalid event_type
non-NULL	An array terminated with the value AST_EVENT_IE_END

struct ast_security_event_ie_type* ast_security_event_get_required_ies ( const enum ast_security_event_type event_type ) [read]

Get the list of required IEs for a given security event sub-type.

Parameters:

[in] event_type security event sub-type

Return values:

NULL	invalid event_type
non-NULL	An array terminated with the value AST_EVENT_IE_END

int ast_security_event_report ( const struct ast_security_event_common * sec )

Report a security event.

Parameters:

[in] sec security event data. Callers of this function should never declare an instance of ast_security_event_common directly. The argument should be an instance of a specific security event descriptor which has ast_security_event_common at the very beginning.

Return values:

0	success
non-zero	failure
