To make these * interfaces simple, I did not want the caller to have to pass in a * memory buffer, but having libical pass out newly allocated memory * makes it difficult to de-allocate the memory. * * The ring buffer in this scheme makes it possible for libical to pass * out references to memory which the caller does not own, and be able * to de-allocate the memory later. The ring allows libical to have * several buffers active simultaneously, which is handy when creating * string representations of components. */ #define ICALMEMORY_C #ifdef HAVE_CONFIG_H #include "config.h" #endif #ifdef DMALLOC #include "dmalloc.h" #endif #include "icalmemory.h" #include "icalerror.h" #include <stdio.h> /* for printf (debugging) */ #include <stdlib.h> /* for malloc, realloc */ #include <string.h> /* for memset(), strdup */ #ifdef WIN32 #include <windows.h> #endif -#define BUFFER_RING_SIZE 100 +#define BUFFER_RING_SIZE 25 #define MIN_BUFFER_SIZE 64 /* HACK.
