poolCreateWithOptions method

int poolCreateWithOptions(String connectionString, int maxSize, { String? optionsJson, })

Creates a pool with explicit eviction/timeout options (v3.0).

optionsJson keys (all optional, in milliseconds): idle_timeout_ms, max_lifetime_ms, connection_timeout_ms. Returns 0 on failure or when the FFI is not available.

Implementation

int poolCreateWithOptions(
  String connectionString,
  int maxSize, {
  String? optionsJson,
}) {
  if (!_bindings.supportsPoolCreateWithOptions) return 0;
  final connStrPtr = connectionString.toNativeUtf8();
  final optsPtr = optionsJson?.toNativeUtf8().cast<bindings.Utf8>();
  try {
    return _bindings.odbc_pool_create_with_options(
      connStrPtr.cast<bindings.Utf8>(),
      maxSize,
      optsPtr,
    );
  } finally {
    malloc.free(connStrPtr);
    if (optsPtr != null) {
      malloc.free(optsPtr.cast<Utf8>());
    }
  }
}
