| Allocate new PtpRuntime based on bitfield options - see PtpConnType. | |
| PUB void | ptp_reset (struct PtpRuntime *r) |

| Init PtpRuntime locally - uses default recommended settings (USB) | |
| PUB void | ptp_close (struct PtpRuntime *r) |
| Frees PtpRuntime data buffer - doesn't free the actual structure, or device info (yet) | |
| PUB int | ptp_send (struct PtpRuntime *r, struct PtpCommand *cmd) |
| Send a command request to the device with no data phase. | |
| PUB int | ptp_send_data (struct PtpRuntime *r, const struct PtpCommand *cmd, const void *data, unsigned int length) |
