void(* DBusFreeFunction)(void *memory)
The type of a function which frees a block of memory.
Definition: dbus-memory.h:65
void dbus_free(void *memory)
Frees a block of memory previously allocated by dbus_malloc() or dbus_malloc0().
Definition: dbus-memory.c:710
#define DBUS_BEGIN_DECLS
Macro used prior to declaring functions in the D-Bus header files.
void * dbus_malloc(size_t bytes)
Allocates the given number of bytes, as with standard malloc().
Definition: dbus-memory.c:470
void dbus_free_string_array(char **str_array)
Frees a NULL-terminated array of strings.
Definition: dbus-memory.c:758
void dbus_shutdown(void)
Frees all memory allocated internally by libdbus and reverses the effects of dbus_threads_init().
Definition: dbus-memory.c:906
void * dbus_malloc0(size_t bytes)
Allocates the given number of bytes, as with standard malloc(), but all bytes are initialized to zero...
Definition: dbus-memory.c:540
void * dbus_realloc(void *memory, size_t bytes)
Resizes a block of memory previously allocated by dbus_malloc() or dbus_malloc0().
Definition: dbus-memory.c:610
#define DBUS_END_DECLS
Macro used after declaring functions in the D-Bus header files.
