Elemental Intrinsic Function (Specific): Allocates a block of memory. This is a specific function that has no generic function associated with it. It must not be passed as an actual argument.
Syntax
result = MALLOC (size)
size
(Input) Must be of type integer. This value is the size (in bytes) of
memory to be allocated.
Results
The result type is INTEGER(4) on on IA-32 architecture; INTEGER(8) on Intel® 64 and IA-64 architectures. The result is the starting address of the allocated memory. The memory allocated can be freed by using the FREE intrinsic function.
Example
INTEGER(4) SIZE
REAL(4) STORAGE(*)
POINTER (ADDR, STORAGE) ! ADDR will point to STORAGE
SIZE = 1024 ! Size in bytes
ADDR = MALLOC(SIZE) ! Allocate the memory
CALL FREE(ADDR) ! Free it
