gzopen
Name
gzopen — Opens or creates a gzip file of the
specified file name.
Synopsis
int gzopen(filename, Mode[, use_include_path]);
string filename: File to
open or create
string Mode: File mode
int use_include_path
(optional): Search the include path for the file
Returns
File pointer on success or FALSE on error
Description
If the file is opened or created successfully, a file
identifier is returned which can be passed to other gz
functions. The file mode is similar to that for fopen()
but with several significant differences. Parameters
commonly used in the GNU gzip program can also be
incorporated in the file mode. You should view any gzip
Unix man page for more details. For example w - write to
a file r - read from a file w9 - write to a file with
compression level set to 9 w9f - write filtered data with
a compression level of 9 w9fh - write filtered data with
a compression level of 9 with Huffman compression. If
use_include_path is set to TRUE the function also
searches the include path for the file specified.
