<title>Description</title>
<para>The functions <function>ne_malloc</function>,
<function>ne_calloc</function>, <function>ne_realloc</function>,
<function>ne_strdup</function> and <function>ne_strdnup</function>
provide wrappers for the equivalent functions in the standard C
library. The wrappers provide the extra guarantee that if the C
library equivalent returns &null; when no memory is available, an
optional callback will be called, and the library will then call
<function>abort</function>().</para>
<para><function>ne_oom_callback</function> registers a callback
which will be invoked if an out of memory error is detected.</para>
</refsect1>

<title>Notes</title>
<para>If the operating system uses optimistic memory
allocation, the C library memory allocation routines will not return
&null;, so it is not possible to gracefully handle memory allocation
failures.</para>
