Example
GL
Returns the length of the current message in multiples of 4 Kbytes (blocks).
The returned value includes the message directory information (64 bytes for the first block and 32 bytes
for every other block), the message data, and the entire last block of the message, even if the message
occupies only a portion of the last block. Since a memory block includes 4096 bytes, the returned length
may be bigger than the actual message length by up to 4095 bytes. The minimum length of a message
is one block.
Example
GMS
Returns the total remaining memory blocks as a 16bit unsigned integer. The parameter type must be 0.
The estimated remaining recording time may be calculated as follows:
Time = (Num_of_blocks x 4096 x 8) / (Compression_rate x 1000)
This estimate assumes no silence compression: a real recording may be longer, according to the
amount of silence detected and compressed.
