malloc(3C) malloc(3C)
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 INFLUENCES sec-
tion of this man page for details.
