Binary I/O utility. In real world you sometimes want to treat
binary port like textual port (e.g. get-line
for binary port).
This library exports those convenient procedures
in must be binary input port.
Reads a bytevector from in until it hits the eol data. _eol_can be multiple length such as #vu8(#x0d #x0a)
. Default value is
#vu8(#x0a)
If keyword argument transcoder is given, then returning value will be
converted to string.
Re-exported procedure from (sagittarius)
for convenience. See
Sagittarius extensions.
out must be binary output port. endian must be a value
returned from endianness
macro.
Write v to out as unsigned/signed 16/32/64 bit integer or 32/64 bit floating number.

in must be binary input port. endian must be a value
returned from endianness
macro.
Read a number from in as unsigned/signed 16/32/64 bit integer or 32/64 bit floating number.
Default binary input port requires bytevector however if users want to handle bigger data then it would not be suitable. Chunk buffered port is a buffered port which buffer is chunks of bytevector so that it doesn't allocate huge memory.
Creates chunk buffered port.
->chunks must be a procedure which takes one argument, chunk-size. And must return a list of bytevectors which size is chunk-size except the last element.
The keyword argument chunk-size is specified then it must be a positive
integer. By default +default-chunk-size+
is used.
Default chunk size of chunk buffered port.
Creates chunk buffered port from given iport.
iport must be a binary input port.
The keyword argument threshold is specified, it must be a positive integer, then the procedure only reads the number of threshold bytes from iport.
