rewind | Rewind is an intelligent archivist

I get a weird problem when running my code, I had a perfectly running code, in order to improve it I coded a little obj file loader function (which seems to work fine even if, at the moment it is not impacting the end result of the code).

The problem is, in this function I use malloc() to create tables and, due to this, I need to free() the memory at the end of the function, this free(some_pointers) don't work and mess up the whole code. I need to tell you that I'm 100% sure this line is the one causing the problem because if I remove it everything work fine (but the memory is still allocated). To sum up, in a function:

*I allocate memory (double *x = malloc(sizeof(double)*integer);)

*I'm modifying this memory (until here everything work fine)

*I free the memory free(x); (adding this line cause the program to crash)

As asked here's the full code of my function:

I'm trying to download videos with a script into a predefined directory:

I want to write a program that counts the frequency of all characters in stdin. My code:

I'm trying to decrypt a message encrypted with AES 192 ECB and getting a segmentation fault and don't know where to look anymore. I know ECB is unsafe, but it is not for a production application.

• I already checked my readFile method, it works (I wrote the ciphre back into a file and checked with the diff tool)
• The key is 24 Bytes long (checked with ls and hexdump)
• ECB has no IV-Vector as far as I know, so I have set it to NULL
• for the decryption part I used the example at https://wiki.openssl.org/index.php/EVP_Symmetric_Encryption_and_Decryption to get started
• I think the problem is at EVP_DecryptUpdate
• I tried to track it down further with gdb but I have no experience with this and only got

0x00007ffff798089d in ?? () from /usr/lib64/libcrypto.so.1.1

Thank you for your time.

I'm a freshman in university and currently learning the C language. Last night I've just found really big problem with my code but there's nothing I could fix with my terrible skills... can you help me to solve this?

(condition)

• you are trying to login with id / pw and only have 3 chances.
• there are 5 id's and pw's on each.
• if id does not exist, print id does not exist.
• if id exists but pw does not match, print pw does not match.
• if id and pw match, print login successful and exit program.

is there any way to loop the strcmp functions which marked?

Here's code below.

I would like to know how to make the ADB adjust the accessibility focus while Talkback is on. I have tried:

Dear Stackoverflow team, I'm impressed that after a bunch of hours digging the forum I still can't find any question/answer similar to my problem :

I have a GeoJson with a lot of Points features. I collect all Points (green in my example, see figure below) that follow some specification (distance between each of them)

Initial Data:

and I want to link all of them to build a Polygon (which represent an area).

What I'm looking for :

Or Solution accepted :

So I collect all coordinates from these Points, and to be sure the Polygon follows the GeoJson requirements, I'm using the "rewind" function

This was the result of my experiments with bytea with postgreSQL and libpq. The result file I am creating with the recieved data is double sized than the original uploaded plus 2 bytes (picture.png). I can not understand exactly how many operations I am doing incorrectly because the procedure is quite confusing for my critter brain. Any help or advice will be a big help for me, thank you in advance.

you can find the solution a little below

I added some controls like rewind or reload to the video on my page but I want these added controls to fade in/out like default controls of video by moving the mouse(fade in) and stop moving after 2sec(fade out).
