struct fr_dbuff_t

Definition at line 41 of file merged_model.c.

Data Fields
uint8_t * p

◆ fr_dict_attr_flags_t

struct fr_dict_attr_flags_t

Values of the encryption flags.

Definition at line 139 of file merged_model.c.

Data Fields
unsigned int array: 1 Pack multiples into 1 attr.
unsigned int counter: 1 integer attribute is actually an impulse / counter
unsigned int extra: 1 really "subtype is used by dict, not by protocol"
unsigned int has_value: 1 Has a value.
unsigned int: 1 is a local variable
unsigned int internal: 1 Internal attribute, should not be received in protocol packets, should not be encoded.
unsigned int is_alias: 1 This isn't a real attribute, it's a reference to to one.
unsigned int is_known_width: 1 is treated as if it has a known width for structs
unsigned int is_raw: 1 This dictionary attribute was constructed from a known attribute to allow the user to assign octets values directly.

See .is_unknown to determine if it is ephemeral.

unsigned int is_root: 1 Is root of a dictionary.
unsigned int is_unknown: 1 This dictionary attribute is ephemeral and not part of the main dictionary.
unsigned int is_unsigned: 1 hackity hack for dates and time deltas
uint8_t length length of the attribute
unsigned int name_only: 1 this attribute should always be referred to by name, not by number
unsigned int secret: 1 this attribute should be omitted in debug mode
uint8_t subtype protocol-specific values, OR key fields
uint8_t type_size For TLV2 and root attributes.

◆ fr_dict_attr_t

struct fr_dict_attr_t

Definition at line 133 of file merged_model.c.

◆ fr_dict_t

struct fr_dict_t

Definition at line 198 of file merged_model.c.

◆ fr_ipaddr_t

struct fr_ipaddr_t

IPv4/6 prefix.

Abstraction around the standard in_addr/in6_addr structures to support address family agnostic functions.

Definition at line 272 of file merged_model.c.

Data Fields
union fr_ipaddr_t addr
int af Address family.
uint8_t prefix Prefix length - Between 0-32 for IPv4 and 0-128 for IPv6.
uint32_t scope_id A host may have multiple link-local interfaces the scope ID allows the application to specify which of those interfaces the IP applies to.

A special scope_id of zero means that any interface of a given scope can be used.

◆ fr_sbuff_escape_rules_t

struct fr_sbuff_escape_rules_t

Definition at line 234 of file merged_model.c.

◆ fr_sbuff_t

struct fr_sbuff_t

Definition at line 37 of file merged_model.c.

char * p

◆ fr_sbuff_term_t

struct fr_sbuff_term_t

Set of terminal elements.

The elements MUST be listed in sorted order. If the inputs are not sorted, then all kinds of things will break.

Definition at line 161 of file merged_model.c.

+ Collaboration diagram for fr_sbuff_term_t:
Data Fields
fr_sbuff_term_elem_t * elem A sorted list of terminal strings.

◆ fr_sbuff_unescape_rules_t

struct fr_sbuff_unescape_rules_t

Set of parsing rules for *unescape_until functions.

Definition at line 163 of file merged_model.c.

Data Fields
char chr Character at the start of an escape sequence.
bool do_hex Process hex sequences i.e.
\x<hex><hex>.
bool do_oct Process oct sequences i.e.
\<oct><oct><oct>.
char const * name Name for rule set to aid we debugging.
bool skip[UINT8_MAX+1] Characters that are escaped, but left in the output along with the escape character.

This is useful where we need to interpret escape sequences for parsing, but where the string will be passed off to a 3rd party library which will need to interpret the same sequences.

char subs[UINT8_MAX+1] Special characters and their substitutions.

Indexed by the printable representation i.e. 'n' for
.
