Forums Bug Reports Helpfile: $decompress

Found a little annoying bug there in the helpfile when reading about $compress and $decompress.

QUOTE
$compress(file|&bvar, blN)
$decompress(file|&bvar)
Compresses the specified file or binary variable. The result is raw compressed data.

Where b indicates a binary variable in the first parameter, and lN sets a compression level of 1 to 6 (default is 6). Returns 1 for sucess, 0 for failure.

It does not say that $decompress need a second parameter, which it does.

$decompress doesnt require any additional parameters.

$compress(file.txt)
$decompress(file.txt)

Work wonderfully here.

Eamonn.

$decompress can take a second parameter though.

The format is really:
$compress(file|&bvar, blN)
$decompress(file|&bvar, b)

with second parameters being optional in both cases.

It can yes, but it does nothing, since $decompress automatically "assesses" (sp), the degree of compression ($compress(file,n)) and decompresses.

As if it didnt then you should be able to do,

$compress(file,2)
$decompress(file,1)

And it still be compressed to 1 degree, but it isnt, its decompressed.

Eamonn.

Yes the level makes no difference, I didn't include that in the listing. The b parameter is still necessary to decompress binary variables.
