Field Documentation

data

u8* GF_Blob::data

data block of blob

size

u32 GF_Blob::size

size of blob

flags

u32 GF_Blob::flags

blob flags

mx

struct __tag_mutex* GF_Blob::mx

blob mutex for multi-thread access

last_modification_time

u64 GF_Blob::last_modification_time

last blob modification time (write access) in microsec , 0 if unknown

range_valid

GF_BlobRangeStatus(* GF_Blob::range_valid) (struct __gf_blob *blob, u64 start, u32 *size)

function used to query if a range of a blob in transfer is valid. If NULL, any range is invalid until transfer is done when set this function overrides the blob flags for gf_blob_query_range size is updated to the maximum number of consecutive bytes starting from the goven offset

range_udta

void* GF_Blob::range_udta

private data for range_valid function
