Hi.

I was reading some articles about static and dynamic memory allocation and there is something I don`t understand.

As I read, in assembly is it possible to extend the space used on the...

Thank you very much for your help.

Hi.

I started to read some documentations and tutorials about file system implementations, and there is something I don`t understand. How superblock, inode table, bitmaps etc are read from the...

Hi.

I need to parse a header read from a socket, which has the following structure.

Bit 1. indicating if this is the final fragment of a message
Bit 2,3,4. is 0
Bit 5,6,7,8. is an opcode,...

I didn`t say I like object oriented languages, I only said that I used some of them at work. In fact I don`t care if it`s oo, procedural, structural or anything else, as long as the code is clean,...

You can use getchar() at the end of your main function.

Hi. I`ve written some smaller projects in C, like programs which were listening on a specified port, and parsed coordinates coming from a gps device, or mini chat servers, so I know how to do some...

Hi.

I have the following code:



char file_path[256];
...
handle = dlopen(file_path, RTLD_LAZY);
...

I just changed the module = malloc(sizeof(module_t *)) to module = malloc( sizeof(*module) ); like you said, and the errors I`ve been having just gone away.

Thank you very much for your help.

I ran my program through valgrind, and saw the errors about the memory corruption. I`ve also corrected some other errors too, but there are two more errors left, and I can`t figure out what am I...

I didn`t want to leave the malloc(1) in my code, just wanted to see what happens, and when I saw that it still works, I didn`t understand why. I will run my application through valgrind, just out of...

Thank you.

I just added the following lines to my code.



#define MODULES_PREFIX "mod_"

typedef struct
{
char *name;
void *handle; //the handler returned by dlopen

I wanted to limit the use of mallocs, to save some execution time, but in this case I guess it is too a solution. Thank you for your reply.

Thank you all for the quick replies. They helped me a lot.

Hi. I have the following function which in the future will load all of the .so modules in a given directory with dlopen, for the moment it only lists the sub directories within "MODULES_PATH", and...

I finally solved it. I changed the media_t structure so all the members are statically allocated. Now it looks like this:



typedef struct
{
char title[128];
char artist[128];
char...

This way it works, so the problem is somewhere else in my application. Thanks for your help, and I will let you know if I solved it, and how.

Hi, and thanks for the reply.

I changed the code, so now it looks like this;



media->title = malloc(31); memset(media->title, 0, 31);
media->artist = malloc(31); memset(media->artist, 0,...

I have a function which reads headers from mp3 files, and extracts the title, artist, album etc. The code looks like this:



typedef struct
{
char *title;
char *artist;
char *album;
}...

Thank you.

Hi.

I have the following code in my application:



#define PORT 1234
#define HOST "http://example.com:1234"

Thank you very much for the replies.
Now I understand the role of these kinds of attributes.

Have a good day.

Hi. I was browsing through the php source code, and I found the following function prototype.

PHPAPI char *php_strtoupper(char *s, size_t len);

I saw this kind of declaration in many source...
