Might have interference in enum dump table. For example "ExpCompensation" is canon, and "Mode" is Fujifilm. Probably will switch to having vendors in the string.

Hi @petabyt @etra0 !

When I try to build I receive following error:

Any tips?

Hi!

@petabyt

I am trying the following code:

#include <stdio.h>
#include <camlib.h>

int main(int argc, char** argv) {
    struct PtpRuntime ptp;
    ptp_generic_init(&ptp);

    char buffer[PTP_BIND_DEFAULT_SIZE];
    int r = bind_run(&ptp, "ptp_init", buffer, sizeof(buffer));
    printf("ptp_init: %s\n", buffer);

    r = bind_run(&ptp, "ptp_connect", buffer, sizeof(buffer));
    printf("ptp_connect: %s\n", buffer);

    r = bind_run(&ptp, "ptp_open_session", buffer, sizeof(buffer));
    printf("ptp_open_session: %s\n", buffer);

    r = bind_run(&ptp, "ptp_get_device_info", buffer, sizeof(buffer));
    printf("ptp_get_device_info: %s\n", buffer);

    r = bind_run(&ptp, "ptp_close_session", buffer, sizeof(buffer));
    printf("ptp_close_session: %s\n", buffer);

    r = bind_run(&ptp, "ptp_disconnect", buffer, sizeof(buffer));
    printf("ptp_disconnect: %s\n", buffer);

    ptp_generic_close(&ptp);
}

Which unfortunately ends up with segmentation fault on ptp_get_device_info:

ptp_init: {"error": 0, "buffer": 8000000}
Initializing USB...
Vendor ID: 4A9, Product ID: 32B4
Endpoint IN addr: 0x81
Endpoint OUT addr: 0x2
Endpoint INT addr: 0x83
ptp_connect: {"error": 0}
send_bulk_packets 0x1002 (PTP_OC_OpenSession)
send_bulk_packet: Sent 16 bytes
recieve_bulk_packets: Read 12 bytes
recieve_bulk_packets: Return code: 0x2001
ptp_open_session: {"error": 0}
Segmentation fault

Any idea, where is the problem? Did I maybe miss something?

BR,

Ladislav

I wrote "recieve" in around 100 different places in this codebase, I apologize
If you were feel useless, know that I won the spelling bee 3 times and still can't spell 2nd grade words

The link to the documentation in your readme.md is broken.
Right now it goes to...
https://danielc.dev/camlib-docs/

Poking around a bit on your site, I think maybe it's supposed to go to...
https://danielc.dev/camlib/

And also, python bindings would be great for people like me who suck at computers :)
