As an AIX SysAdmin for the last ~30 years i can tell you: nothing is even "close to AIX". Sorry to say that but to learn AIX you need AIX, nothing else. The best (and cheapest) you may try is to buy...

main and getopt aren't variadic, they're array-based.

So one solution could be converting the variadic arguments into an array.

#include <stdio.h>
#include <stdlib.h>
#include <stdarg.h>

The thread title of this thread has been changed from "Listing files ftom Octobre 4th is not accurate" to "Listing files from October 4th is not accurate" hoping to make searches for similar threads...

Is anyone actively learning, auditing or participating (for credit) at edX (https://www.edx.org/)?




There are some really great science and engineering programs there and they are all free to...

Welcome to the forum.


Please DON'T hijack others' threads, but open your own for your (new) questions. I did this for you with this post.

You have to follow the method I showed to-the-letter. (*arr[a][b])[c] is not the same as (*arr)[a][b][c].

void arrbyptr(int (*ptr[2][2])[2]) {
int result, i, j, k;
for ( i = 0; i <...

Use gdb. We could probably point you to your problem but you need to learn how to use gdb.
the commands you need are:

compile & debug with
gcc filename.c -Wall -g -o filename
gdb filename...

Here's how I had to use it:

#include <stdio.h>

void arrbyptr(int (*ptr[2][2])[2]) {

printf("[0][0][0]=%d,[0][0][1]=%d,[0][1][0]=%d,[0][1][1]=%d\n",
(*ptr)[0][0][0],...

Calling random seed repeatedly is sort of overdoing it - or, in your case, even counterproductive. Do it once at program startup - if at all necessary as the compiler / interpreter may do it for you....

The POSIX standard requires that type char in the C language must be an 8-bit type. The C Standard doesn't specify whether type char is signed or unsigned. So the range of values that can be...

for (j = 0; j < data[INPUT_BUFF]; j++){ This is wrong.

for (j = 0; data[j] != 0; j++){ This is probably what you want.

switch(data[j]){
case 0:
...
case 1:
...
case...

int * isn't enough information for C to know what kind of array is being pointed to. That assumes a single integer or 1D array.

int *matrix[size][size] does not make pointers to 2d arrays -- it...

That it compiled without errors only means your program is correct grammatically, the same way "my hovercraft is full of eels" will pass a grammar check but not help Belgians communicate with...

Did you consider making c a pointer to int array?

I do think you're on the right track, or a right track, there being more than one way to skin a cat.

Sorry, I got turned around. curl handles the outgoing request, not the incoming one. You'd...

There's no "native" one-liners for HTTP in C. C doesn't handle files natively, let alone HTTP. This lack of dependencies is why you can write kernels in it -- and write entire languages like ruby,...

You might also consider running a complete proxy such as tinyproxy.

You forgot to include stdio.h for printf, etc, which is a crash-causing error in 64-bit programs.

Most major problem:

char *strip;

...

strcpy(strip,buf);

You use strip without giving...

The man page for the regcomp utility (try man 1 regcomp) on your system should tell you everything you need to know. If you get back something similar to:
No entry for regcomp in section 1 of the...

You're very close... In the line:
if(regcomp(&re , newhold, REG_NOMATCH) != 0 ){
REG_NOMATCH is a defined to be a return code for regexec() indicating that it did not find a match; it is not...

Take the contents of the string variable (newhold) you constructed, print it, and try it as a pattern for grep as a console command. You also need to check the return code from regexec in case...

You can "statically" pre-compile to a text file: use the regcomp command - not a C call. It creates the compiled buffer you need in a file. I typically use maybe a dozen of ptr-compiles in a simple...

If you don't need too many different regexes but could repeatedly (re)use a handful of them on many different strings, compile each of them once into a new pattern buffer, and run all the...

There are two basic sets of pattern matching: files and strings

fnmatch() is used to match wildcards like ? and * in file name patterns.
regcomp(), regexec(), regfree() are called in that order...

Looking at strstr's man page, I can't see it would accept any wildcard char nor regex. So you might need to build you own grep routine?
