Compress a String and Save as a Gzip File

See more Gzip Examples

This example demonstrates how to use the CompressStringToFile method to compress a string and write the result directly to a Gzip (.gz) file.

The input string is first converted to its byte representation using the specified character set (in this case, UTF-8). The resulting bytes are then compressed using the Gzip format, and the compressed output is written directly to the specified file.

This method is convenient when you want to generate a compressed file from in-memory text without needing intermediate objects such as BinData or StringBuilder.

set gzip [new_CkGzip]

# The string to be compressed:
set inputStr "The quick brown fox jumps over the lazy dog."

# Compress the string using UTF-8 and write to a file:
set success [CkGzip_CompressStringToFile $gzip $inputStr "utf-8" "output.gz"]
if {$success == 0} then {
    puts [CkGzip_lastErrorText $gzip]
    delete_CkGzip $gzip
    exit
}

puts "Compression successful."
puts "Gzip file written to output.gz"

delete_CkGzip $gzip
