Allocating storage

Allocating storage: C: Data Structures, Pointers, and File Systems
Allocating storage: C: Data Structures, Pointers, and File Systems

The malloc() function allocates a chunk of memory, which is saved in a pointer variable. To ensure that malloc() allocated memory, compare the return value with the NULL pointer constant, which is returned when the allocation fails. The malloc() function requires an argument equal to the amount of memory requested. Use the sizeof operator to calculate the proper storage based on the storage buffer's data type. When you're done using an allocated chunk of memory, use the free() function to de-allocate it.
