Used to select the type of data format to use for GZlibDecompressor and GZlibCompressor.
| deflate compression with zlib header | |
| gzip file format | |
| deflate compression with no header |
Since 2.24
GZlibCompressor * g_zlib_compressor_new (GZlibCompressorFormat format,int level);
Creates a new GZlibCompressor.
|
The format to use for the compressed data |
|
compression level (0-9), -1 for default |
Returns : |
a new GZlibCompressor |
Since 2.24
GFileInfo * g_zlib_compressor_get_file_info (GZlibCompressor *compressor);
Returns the "file-info" property.
|
a GZlibCompressor |
Returns : |
a GFileInfo, or NULL. [transfer none]
|
Since 2.26
void g_zlib_compressor_set_file_info (GZlibCompressor *compressor,GFileInfo *file_info);
Sets file_info in compressor. If non-NULL, and compressor's
"format" property is G_ZLIB_COMPRESSOR_FORMAT_GZIP,
it will be used to set the file name and modification time in
the GZIP header of the compressed data.
Note: it is an error to call this function while a compression is in
progress; it may only be called immediately after creation of compressor,
or after resetting it with g_converter_reset().

|
a GFileInfo. [allow-none] |
Since 2.26
"file-info" property"file-info" GFileInfo* : Read / Write
If set to a non-NULL GFileInfo object, and "format" is
G_ZLIB_COMPRESSOR_FORMAT_GZIP, the compressor will write the file name
and modification time from the file info to the the GZIP header.
Since 2.26
"format" property"format" GZlibCompressorFormat : Read / Write / Construct Only
The format of the compressed data.
Default value: G_ZLIB_COMPRESSOR_FORMAT_ZLIB
"level" property"level" gint : Read / Write / Construct Only
The level of compression from 0 (no compression) to 9 (most compression), -1 for the default level.
Allowed values: [G_MAXULONG,9]
Default value: -1
