Macro Definition Documentation

◆ LOG

#define LOG (   kind,
  ... 
)     GNUNET_log (kind, __VA_ARGS__)

Generic logging.

Definition at line 44 of file gnunet-service-testbed.h.

◆ LOG_DEBUG

#define LOG_DEBUG (   ...)     LOG (GNUNET_ERROR_TYPE_DEBUG, __VA_ARGS__)

Debug logging.

Definition at line 50 of file gnunet-service-testbed.h.

◆ LIST_GROW_STEP

#define LIST_GROW_STEP   10

By how much should the arrays lists grow.

Definition at line 56 of file gnunet-service-testbed.h.

◆ VALID_HOST_ID

#define VALID_HOST_ID (   id)     (((id) < GST_host_list_size) && (NULL != GST_host_list[id]))

Condition to check if host id is valid.

Definition at line 473 of file gnunet-service-testbed.h.

◆ VALID_PEER_ID

#define VALID_PEER_ID (   id)     (((id) < GST_peer_list_size) && (NULL != GST_peer_list[id]))

Condition to check if peer id is valid.

Definition at line 479 of file gnunet-service-testbed.h.

◆ GST_array_grow_large_enough

#define GST_array_grow_large_enough (   ptr,
  size,
  accommodate_size 
)
Value:
do \
{ \
unsigned int growth_size; \
GNUNET_assert (size <= accommodate_size); \
growth_size = size; \
while (growth_size <= accommodate_size) \
growth_size += LIST_GROW_STEP; \
GNUNET_array_grow (ptr, size, growth_size); \
GNUNET_assert (size > accommodate_size); \
} while (0)
#define LIST_GROW_STEP
By how much should the arrays lists grow.
static unsigned int size
Size of the "table".
Definition: peer.c:67

Similar to GNUNET_array_grow(); however instead of calling GNUNET_array_grow() several times we call it only once.

The array is also made to grow in steps of LIST_GROW_STEP.

Parameters
ptrthe array pointer to grow
sizethe size of array
accommodate_sizethe size which the array has to accommdate; after this call the array will be big enough to accommdate sizes up to accommodate_size
