JR_ARR_KVDescription
Conditionally parse a JSON array if key matches expected name.
Parameters
| Name | Direction | Description |
|---|---|---|
si | in,out | Stream iterator to read from. |
k | in | Expected key name (C-string). |
Usage example (from documentation)
JR_ARR_KV(si, "list", {
JR_INT(si, val);
VecPush(&arr, val);
});
Success
Array parsed if key matched
Failure
No-op if key does not match
