HP-UX Reference (11i v2 04/09) - 3 Library Functions A-M (vol 6)

malloc(3C) malloc(3C)
Obsolescent Interfaces
memorymap() has been deprecated at HP-UX 11i Version 1 and is now obsolete. The
mallinfo()
function is more useful for malloc statistics.
Compatibility
The only external difference between the old malloc(3X) allocator and the malloc(3C) allocator is that the
old allocator would return a NULL pointer for a request of zero bytes. The malloc (3C) allocator returns a
valid memory address. This is not a concern for most applications.
By default, SBA (Small Block Allocation) is turned on for Itanium-based systems and is turned off for
PA-RISC systems. This was due to performance concerns. Please refer to the EXTERNAL INFLU-
ENCES section of this manpage for details.
