check_index_info()

static int check_index_info ( void *  cls, const struct IndexInfoMessage *  iim  )

static

Check validity of response from the FS service with information about indexed files.

Parameters

cls	closure (of type struct GNUNET_FS_GetIndexedContext *)
iim	message with indexing information

handle_index_info()

static void handle_index_info ( void *  cls, const struct IndexInfoMessage *  iim  )

static

Function called on each response from the FS service with information about indexed files.

Parameters

cls	closure (of type struct GNUNET_FS_GetIndexedContext *)
iim	message with indexing information

Definition at line 119 of file fs_list_indexed.c.

Here is the call graph for this function:

mq_error_handler()

static void mq_error_handler ( void *  cls, enum GNUNET_MQ_Error  error  )

static

Generic error handler, called with the appropriate error code and the same closure specified at the creation of the message queue.

Not every message queue implementation supports an error handler.

Parameters

cls	closure with the struct GNUNET_FS_GetIndexedContent *
error	error code
