RouterOS API Header file (mikrotik-api.h)

This is the API header file.

Notes:

•• DEBUG flag is defined for debugging purposes...generates alot of internal data via printf

•• DONE, TRAP and FATAL constants are defined

•• Sentence and Block structs are defined.

•• Each word in a sentence is stored as a string. Sentence structs contain individual API words (stored as an array

of strings).

•• Block structs represent the full API response...an array of sentences. Blocks are not defined in the Mikrotik

API specs, but are a convenient way to represent a full API response in the context of this implementation.

#include "md5.h"

#define DEBUG 0

#define DONE 1

#define TRAP 2

#define FATAL 3

struct Sentence {

char **szSentence; // array of strings representing individual words

int iLength; // length of szSentence (number of array elements)

int iReturnValue; // return value of sentence reads from API

};

struct Block {

1 2 ... 212 213 214 215 216 217 218 219 220 221 222 ... 279 280
