void ne_oom_callback(void (*callback)(void));

Description

The functions ne_malloc, ne_calloc, ne_realloc, ne_strdup and ne_strdnup 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 abort().

ne_oom_callback registers a callback which will be invoked if an out of memory error is detected.

Notes

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.
