MORECORE_FAILURE (default: -1)

The value returned upon failure of MORECORE.

MORECORE_CLEARS (default 1)

True (1) if the routine mapped to MORECORE zeroes out memory (which

holds for sbrk).

The degree to which the routine mapped to MORECORE zeroes out
|
||||
memory: never (0), only for newly allocated space (1) or always
|

(2). The distinction between (1) and (2) is necessary because on

some systems, if the application first decrements and then

increments the break value, the contents of the reallocated space
|

are unspecified.
