◆ conv

GNUNET_SQ_ResultConverter GNUNET_SQ_ResultSpec::conv

◆ cleaner

GNUNET_SQ_ResultCleanup GNUNET_SQ_ResultSpec::cleaner

Function to clean up result data, NULL if cleanup is not necessary.

◆ cls

void* GNUNET_SQ_ResultSpec::cls

Closure for conv and cleaner.

◆ dst

void* GNUNET_SQ_ResultSpec::dst

◆ dst_size

size_t GNUNET_SQ_ResultSpec::dst_size

Allowed size for the data, 0 for variable-size (in this case, the type of dst is a void ** and we need to allocate a buffer of the right size).

◆ result_size

size_t* GNUNET_SQ_ResultSpec::result_size

Where to store actual size of the result.

If left at NULL, will be made to point to dst_size before conv is called.

unsigned int GNUNET_SQ_ResultSpec::num_params
