Name
ne_malloc, ne_calloc, ne_realloc, ne_strdup, ne_strndup, ne_oom_callback — memory allocation wrappers
Synopsis
#include <ne_alloc.h>
void *ne_malloc( | size_t size); |
void *ne_calloc( | size_t size); |
void *ne_realloc( | void *size, |
| | size_t len); |
char *ne_strdup( | const char *s); |
char *ne_strndup( | const char *s, |
| | size_t size); |
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.
