Write documentation.

[bmusin]

Hi. Could you please make documentation?
Library is useful but lack of documentation and necessity to read code
in order to use the library is disappointing.
For example, it is not obvious how to extract string value from member.
Thanks.

Have no time now but can share some code

int jsonGetInt64 (cJSON *j, const char *element, int64_t *value) {
int rc = ~0;
cJSON *obj = cJSON_GetObjectItem(j, element);
if (obj) {
if (obj->type == cJSON_Number) {
*value = obj->valueint;
rc = 0;
} else if (obj->type == cJSON_String) {
char ch;
int64_t t;
if (sscanf(obj->valuestring, "%" PRId64 "%c", &t, &ch) == 1) {
*value = t;
rc = 0;
}
} else if (obj->type == cJSON_False) {
*value = 0;
rc = 0;
} else if (obj->type == cJSON_True) {
*value = 1;
rc = 0;
}
}
return rc;
}

int jsonGetDouble (cJSON *j, const char *element, double *value) {
int rc = ~0;
cJSON *obj = cJSON_GetObjectItem(j, element);
if (obj) {
if (obj->type == cJSON_Number) {
*value = obj->valuedouble;
rc = 0;
} else if (obj->type == cJSON_String) {
char ch;
double t;
if (sscanf(obj->valuestring, "%lf%c", &t, &ch) == 1) {
*value = t;
rc = 0;
}
}
}
return rc;
}

int jsonGetString (cJSON _j, const char *element, char *_value) {
int rc = ~0;
*value = NULL;
cJSON *obj = cJSON_GetObjectItem(j, element);
if (obj) {
if (obj->valuestring) {
*value = obj->valuestring;
rc = 0;
}
}
return rc;
}

int jsonGetBoolean (cJSON *j, const char *element, int *value) {
int rc = ~0;
cJSON *obj = cJSON_GetObjectItem(j, element);
if (obj) {
*value = obj->type == cJSON_True;
rc = 0;
}
return rc;
}

I think that the detail you might be missing is that it's just not a very elegant library.
If it's not obvious to you how to extract a string value from a member, then this probably isn't the right library for your purposes.

Can I recommend RapidJSON?

I figured out quickly from source that one should get string from ->valuestring.
That was just my complaint about docs, anyway, thanks.

PS: now have two libraries to choose from ;-)
