Functions

#####ustruct.calcsize(fmt)

Return the number of bytes needed to store the given fmt.

#####ustruct.pack(fmt, v1, v2, ...)

Pack the values v1, v2, ... according to the format string fmt. The return value is a bytes object encoding the values.

#####ustruct.pack_into(fmt, buffer, offset, v1, v2, ...)

Pack the values v1, v2, ... according to the format string fmt into a buffer starting at offset. offset may be negative to count from the end of buffer.

#####ustruct.unpack(fmt, data)

Unpack from the data according to the format string fmt. The return value is a tuple of the unpacked values.

#####ustruct.unpack_from(fmt, data, offset=0)

Unpack from the data starting at offset according to the format string fmt. offset may be negative to count from the end of buffer. The return value is a tuple of the unpacked values.
