Description

GstByteWriter provides a byte writer and reader that can write/read different integer and floating point types to/from a memory buffer. It provides functions for writing/reading signed/unsigned, little/big endian integers of 8, 16, 24, 32 and 64 bits and functions for reading little/big endian floating points numbers of 32 and 64 bits. It also provides functions to write/read NUL-terminated strings in various character encodings.
