GetZone

GetZone Get address of the current heap zone

#include <Memory.h> Memory Manager

THz GetZone( );

returns pointer to a 62-byte Zone record

GetZone returns the address of the start of the current heap zone.

Returns: a 4-byte pointer; the address of a 62-byte Zone record for that

current active heap zone.

Notes: Another method is to access the global variable TheZone (at 0x0118). For

instance, to change the number of master pointers to be allocated via

MoreMasters (i.e., modify a field of the current Zone structure), you

could use:

void MyMoreMasters( numMastPtrs )

short numMastPtrs;

{

short oldMoreMast; /* saved value of moreMast */

oldMoreMast = TheZone -> moreMast;   /* get old value of moreMast */
TheZone -> moreMast = numMastPtrs; /* put the value we want in */

/* zone header */

MoreMasters(); /* allocate the master pointers */

TheZone -> moreMast = oldMoreMast;/* restore old val of moreMast */

}

Use SetZone to make a different zone active.
