size - an unsigned integral value (casted to size_t) which represents the memory block in bytes malloc() Return Value The malloc() function returns: a void pointer to the uninitialized memory block allocated by the function null pointer if allocation fails Note: If the size is zero, the va...
The C stdlib library malloc() function is used for dynamic memory allocation. It allocates or reserves a block of memory of specified number of bytes and returns a pointer to the first byte of the allocated space.The function malloc() is used when the required size of memory is not known...

C Language: malloc function(Allocate Memory Block) In the C Programming Language, the malloc function allocates a block of memory for an array, but it does not clear the block. To allocate and clear the block, use the calloc function....

The malloc() function is a standard library function that allocates a specified amount of memory and returns a pointer to the beginning of this memory block. The syntax for malloc() is as follows: void *malloc(size_t size); Here, size represents the number of bytes to allocate. The func...
The malloc() function returns a pointer to a block of at least size bytes, which is appropriately aligned. The free() function releases a previously allocated block. Its argument is a pointer to a block previously allocated by malloc() or realloc(). The free() function does not set errno...
