bigloo procedure: port->gzip-port input-port [buffer #t]

bigloo procedure: port->zlib-port input-port [buffer #t]

bigloo procedure: port->inflate-port input-port [buffer #t]

These functions take a regular port as input (input-port). They construct a new port that automatically unzip the read characters. The inflate version does not parse a gunzip-header before inflating the content.

bigloo procedure: open-input-inflate-file path [buffer #t]

These function open a gzipped file for input. The file is automatically unzipped when the characters are read. It is equivalent to:

(let ((p (open-input-port path)))
  (port->gzip-port p))

The function open-input-inflate-file is similar to open-input-gzip-file but it does not parse a gunzip-header before inflating the content.

bigloo procedure: gunzip-sendchars input-port output-port

bigloo procedure: inflate-sendchars input-port output-port

Transmit all the characters from the gzipped input-port to the output-port.

Note that the function send-chars can also be used on gzipped input-ports.

bigloo procedure: gunzip-parse-header input-port

Parse the header of input-port. Returns #f if and only if the port is not gzipped.
