@brief POSIX-compatible extended memory handling.
|
|
|
|
xmemory is a small and efficient module offering memory extension
|
|
capabitilies to ANSI C programs running on POSIX-compliant systems. It
|
|
offers several useful features such as memory leak detection, protection for
|
|
free on NULL or unallocated pointers, and virtually unlimited memory space.
|
|
xmemory requires the @c mmap() system call to be implemented in the local C
|
|
library to function. This module has been tested on a number of current Unix
|
|
flavours and is reported to work fine.
|
|
The current limitation is the limited number of pointers it can handle at
|
|
the same time.
|
|
See the documentation attached to this module for more information.
