<!-- ##### SECTION Short_Description ##### -->

Memory allocation and debugging functions.

<!-- ##### SECTION Long_Description ##### -->
<para>

This set of functions is semantically similar functions to standard C
library memory allocation routines.  When memory debugging is enabled
these functions include support to detect buffer overruns.  When
memory debugging is not enabled the allocation and free calls are
wrappers around the standard C allocation routines, and checking
routines are null ops.

</para>

<para>
Memory debugging is enabled when DEBUG_MEM is defined at compilation
time.  On Unix systems, the <filename>configure</filename> script has
a command-line option <option>--enable-debug-mem</option>.  On Win32,
a memory debugging is enabled in the debug configuration.

<!-- ##### MACRO xmalloc ##### -->
<para>
Allocates a block of memory.  Semantically equivalent to malloc().
</para>

@x: size of allocation.


<!-- ##### MACRO xrealloc ##### -->
<para>
Re-sizes a block of memory. Semantically equivalent to realloc().
</para>

@p: Pointer to block to be re-dimensioned.
@x: New size.


<!-- ##### MACRO xstrdup ##### -->
<para>
xmalloc()'s sufficient memory to store @str, copies @str into it, and
returns pointer to new string.  Semantically equivalent to strdup().
</para>

@str:
