explain_malloc_or_die - Allocate and free dynamic memory and report errors
SYNOPSIS
#include <libexplain/malloc.h>
void *explain_malloc_or_die(size_t size);
DESCRIPTION
The explain_malloc_or_die function is used to call the malloc(3) system call. On failure an explanation will be printed to stderr,
obtained from explain_malloc(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
void *result = explain_malloc_or_die(size);
size The size, exactly as to be passed to the malloc(3) system call.
Returns:
This function only returns on success. On failure, prints an explanation and exits.
SEE ALSO malloc(3)
Allocate and free dynamic memory
explain_malloc(3)
explain malloc(3) errors
exit(2) terminate the calling process

DESCRIPTION
The explain_pipe_or_die function is used to call the pipe(2) system call. On failure an explanation will be printed to stderr, obtained
from explain_pipe(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
explain_pipe_or_die(pipefd);
pipefd The pipefd, exactly as to be passed to the pipe(2) system call.
Returns:
This function only returns on success. On failure, prints an explanation and exits.

Did any one knows everything about the unix memory management system and the free() function?
There is no problem when making the dynamic arrays free. The problem is that when trying free the link lists. The free() function does not work when trying to make free the link lists. I would be... (4 Replies)
Hello
This is a simple program i carried out in my machine
i dont know how it is working
#include<alloc.h>
#include<stdio.h>
mian()
{

p= (int*)malloc(1);
for(j=1;j<=580;j++)
{
*p=j;
++p;
}
p=p-580;

Hi All!
Does some one know I am under UNIX system can not allocate more then 1 Mb memory? It broke program down.
Any information would be greatly appreciated.
Thanks. (2 Replies)
Hello!
Is there a C function or system call in AIX that can tell how much free memory
is in the system at a certain moment?
Also, I'd like to know if there are functions that can:
-find the number of processors in the system
-report the network interface activity.
Thank you very much in... (0 Replies)
Is it generally not a good idea in a multithreaded program to make lots of malloc calls (dynamic memory requests) because of the limited nature of the memory heap ?
Out of curiosity (warning it may sound silly), but would using mutexs (mutual exclusion) help to minimise chances of runtime errors... (12 Replies)
Some one please explain me what is Dynamic memory allocation and the use of malloc() function.How do we allocate memory dynamically and also the other way? (3 Replies)
When allocating memory for two different nodes, the resulting memory are the same. Clearly, this will lead to a mistake. This happened in a function. And the process must be in a function.
(gdb) p tree->list
$43 = (node *) 0x8be4180
(gdb) p tree->list
$44 = (node *) 0x8be4180

Just a statement I need some clarification
Im aware that malloc() can be used to create pointers, and free() is used to deallocate dynamic memory, however is free() the ONLY way to dispose of the dynamic memory, because not using free() means the dynamic memory still exists and it may cause some... (1 Reply)
Hi All,
I have a process running on my AIX 5.3 server box. The process runs fine for 5-6days but then crashes. The log file shows malloc failure and the svmon (Virtual memory size), ps -lef (SZ value) are also gradually increasing. But unfortunately MALLOCDEBUG and any other memory debugging... (3 Replies)
Which one is faster among malloc and new?
My understanding is that since new also has to call constructors after allocating memory it must be slower than malloc.
Am I correct? (1 Reply)
Good day! I'm a newbie in C. I'm trying to get an unlimited input from the user using malloc then printing the inputs after the user presses enter. My code works, but there's a warning that I don't know how to fix. Please help me. Thank you.
Here's my code:
