Member Data Documentation

◆ continuous_offset

uint64_t ifhd::v201_v301::FileHeader::continuous_offset

the offset of the first chunk of the continuous section of the file (only needed for IndexedFile::m_nVersionIdWithHistory)

◆ description

int8_t ifhd::v201_v301::FileHeader::description[1912]

common string description. This value is separated into a short and detailed description separated by '
'.

◆ duration

uint64_t ifhd::v201_v301::FileHeader::duration

timestamp of the last chunk in microseconds or nanoseconds resolution (depending on file version < ifhd::v500::version_id).

◆ file_id

uint32_t ifhd::v201_v301::FileHeader::file_id

identifier for every dat-File. intel cpu implementations uses "IFHD" motorola uses "DHFI" see also headerByteOrder

◆ file_time

uint64_t ifhd::v201_v301::FileHeader::file_time

creation time of file in unix seconds since 1/1/1970 00:00:00 UTC (Universal Time Coordinated).

◆ first_chunk_offset

uint64_t ifhd::v201_v301::FileHeader::first_chunk_offset

the file offset of the first chunk (only needed for IndexedFile::m_nVersionIdWithHistory)

◆ header_byte_order

uint8_t ifhd::v201_v301::FileHeader::header_byte_order

endianess of management structures (little or big endian), see also PLATFORM_BYTEORDER_UINT8. every single value within the structures (FileHeader, FileExtension, ChunkHeader ... ) are stored in this corresponding byteorder!

◆ ring_buffer_end_offset

uint64_t ifhd::v201_v301::FileHeader::ring_buffer_end_offset

the end position withing the ring buffer section (only needed for IndexedFile::m_nVersionIdWithHistory)

◆ time_offset

uint64_t ifhd::v201_v301::FileHeader::time_offset

time offset for every time within the file is referred to (timestamp zero) in microseconds or nanoseconds resolution (depending on file version < ifhd::v500::version_id).

◆ version_id

uint32_t ifhd::v201_v301::FileHeader::version_id

format version of dat files, current version is IndexedFile::m_nVersionId or IndexedFile::m_nVersionIdWithHistory
