| 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
