MALLOC

インテル® Fortran コンパイラー 19.0 デベロッパー・ガイドおよびリファレンス

Elemental Intrinsic Function (Generic): Allocates a block of memory. This is a generic function that has no specific function associated with it. It must not be passed as an actual argument.

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 IA-32 architecture; INTEGER(8) on Intel® 64 architecture. 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
