brp_ioiter_create()

BRP_LIB brp_ioiter brp_ioiter_create

(

void

)

Creates an iterator for enumerating all available I/O devices.

This function creates a composite iterator that enumerates all supported I/O protocols (currently USB HID only). The iterator will enumerate all devices across all supported protocols.

For USB HID devices: Enumerates devices with default Baltech VID (0x13AD) and PID ranges (40000-40999, 1000-1999, 0xF001-0xFFFF). Only devices with valid numeric serial numbers and BRP interface (usage_page=0xFF00, usage=1) are included.

The iterator must be destroyed with brp_ioiter_destroy() when done.

Returns

Iterator handle or NULL on failure (e.g., out of memory)

brp_ioiter iter = brp_ioiter_create();
if (iter == NULL) {
    // Handle error
    return;
}

brp_protocol protocol;
while (brp_ioiter_next(iter, &protocol) == BRP_OK && protocol != NULL) {
    // Use protocol
    char* name = brp_get_friendly_name(protocol);
    printf("Found device: %s\n", name ? name : "Unknown");

    // Clean up protocol when done
    brp_destroy(protocol);
}

brp_ioiter_destroy(&iter);
