MALLOC is an C Subroutine that requests the allocation memory. When this call fails, the most common reason is that you're out of memory; it's all been allocated. Unless you're programming this application, this is one of those problems you likely can't fix. Consider powering the system down, unplugging it, waiting 5 minutes and trying again.

What does lag stand for?
Lag isn't an acronym it is just a word. It means to fail to keep up to the pace.
Why did devices like Roomba eventually fail?
Because Rumba costs a small fortune and the really don'y work that well.
What does the prefix in disadvantages mean?
Zendaya and Bella thorne does not like each other they are both sellouts and losers so they suck Fail!
Why does the power supply unit have a fan built?
To keep the power supply cool. If there were no fan the power supply would overheat and fail.
Operating systems never fail in computers?
Operating Systems ALWAYS will fail, it's about how often, not if. The OS on NASA exploratory machines have 'exploded' before and caused some devices to stop working, in spite of the fact that they were written to be very stable and do only one thing; stability is an anathema to computer construction. The more useful (general use) a device is, the less stable it will be.
How do you declare an N-Dimensional array using Malloc?
#include <stdlib.h> int **array1 = malloc(nrows * sizeof(int *)); for(i = 0; i < nrows; i++) array1[i] = malloc(ncolumns * sizeof(int));
What is the difference between allocating memory through heap and malloc?
Nothing, malloc does allocate memory from the heap.
What if happen when you allocate memory by using malloc or calloc when the momory is not available contigiously?
malloc/calloc/realloc will return NULL
What is really meant by malloc and where you will use this malloc?
malloc is a function of the standard c library (stdlib) and it is abbreviation for memory allocate. What this function does is allocates memory in the RAM of computer to store variable data in it. You will use it whenever you need a place to store you temporary data such as an array or structure. To use malloc all you have to do is call malloc and tell it the size of the memory you want. It will then return a pointer to that memory. persumabely if it fails it returns NULL.
What is the malloc function?
The malloc function is one of a group of memory allocation functions; malloc, calloc, realloc, and free. Specifically malloc (size) returns a pointer to a new memory block of at least size bytes, suitably aligned for optimum access for any basic type, or it returns a NULL if the request cannot be satisfied.
Which of libraries calloc belongs?
malloc()
Max memory allocated by malloc in c?
Memory is allocated by malloc from the heap.... so max mem = size of heap that is free...
What is a malloc function in C programming with example?
The malloc() function is part of a class of functions that deal with the allocation of memory on the heap. int *a = malloc (sizeof (int) * 100); /* allocate 100 int's */ if (a == NULL) {...} /* deal with possible malloc failure */ /* use a, either as pointer or as array of 100 ints */ free (a); /* release memory back to the library */
Difference between malloc and alloc?
alloc is used as header file while using malloc and calloc functions in C prog.The definition of malloc function is in the alloc.h file.It's stdlib.h to be more precise
How you use malloc function in c?
void* malloc (size_t bytes); This means that malloc takes an argument which is the size of memory to allocate and returns a pointer to that memory which has been allocated. If the return value is NULL, then the request could not be satisfied. Each call to malloc must be balanced with a corresponding call to free, to release the memory. int pa = NULL; pa = (int*) malloc (sizeof(int) * 1000); /* allocate 1000 ints */ if (pa == NULL) throw exception... ... use pa free (pa); pa = NULL;
What is different between malloc and free?
malloc reserves memory for your use, free removes the reservation done by malloc and makes the memory available for other applications.Note: both of them is a special case of realloc:malloc (n) = realloc (NULL, n)free (p) = realloc (p, 0)
Comparison of C' malloc and free functions with c new and delete operators?
Hi, The difference between new and malloc: 1.The New is a operator however malloc is a function 2.New returns the object type and there is no typecasting required. In malloc type casting should be done as it returns a void*. 3. The new operator can be overloaded however there is no over loading in C and hence Malloc can not be overloaded. 4. Operater New asks for the number of objects to be allocated however in malloc it will ask you for the number of bytes to be allocated. 5. The New operater will return you a exception of memory is not available however in malloc it will return u a NULL. 6. New is a concept for dynamically allocation in OOPS(C++) however malloc is used in C. The difference between the delete and free is as follows: 1. delete is a operator and can be overloaded however free is a function and can not be overloaded. With Regards, Shashiraja Shastry
