Function Documentation

LIBGIFT_EXPORT void* gift_calloc (  size_t  nmemb, size_t  size )

Wrapper for calloc to prevent nmemb 0 or size 0.

LIBGIFT_EXPORT void gift_free (  void *  ptr  )

Dummy wrapper for free to just go along with this scheme.

EXTERN_C_BEGIN LIBGIFT_EXPORT void* gift_malloc (  size_t  size  )

Wrapper for malloc that prevents malloc(0).

LIBGIFT_EXPORT void* gift_memdup (  const void *  ptr, size_t  size )

Similar to strdup, except that it operates on raw memory. I'm baffled why such a function was not provided by the standard.

LIBGIFT_EXPORT void* gift_realloc (  void *  ptr, size_t  size )

Realloc wrapper that prevents some broken implementations of realloc from failing when ptr is NULL or size is 0.
