## 9.3.55 FREE (A)

Description: | Frees a block of memory that is currently allocated.
Class: | Subroutine
Arguments: | A must be of type INTEGER(4) on ia32 processors; INTEGER(8) on Alpha and ia64 processors. This value is the starting address of the memory to be freed, previously allocated by MALLOC (see Section 9.3.92). If the freed address was not previously allocated by MALLOC, or if an address is freed more than once, results are unpredictable.

Examples

Consider the following:

      INTEGER(4) ADDR, SIZE
      SIZE = 1024                   ! Size in bytes
      ADDR = MALLOC(SIZE)           ! Allocate the memory
      CALL FREE(ADDR)               ! Free it
      END
