## Description

GsfInfile and GsfOutfile support for zip files.

## Functions

### gsf_infile_zip_new ()

    GsfInfile *
    gsf_infile_zip_new (GsfInput *source,
                        GError **err);

Opens the root directory of a Zip file.

This adds a reference to `source`.

#### Parameters

source | A base GsfInput |
err | place to store a GError if anything goes wrong. | [allow-none]

#### Returns

the new zip file handler

### gsf_outfile_zip_new ()

    GsfOutfile *
    gsf_outfile_zip_new (GsfOutput *sink,
                         GError **err);

Creates the root directory of a Zip file and manages the addition of children.

This adds a reference to `sink`.

#### Parameters

sink | a GsfOutput to hold the ZIP file |
err | Location to store error, or `NULL`; currently unused. |

#### Returns

the new zip file handler

### gsf_outfile_zip_set_compression_method ()

    gboolean
    gsf_outfile_zip_set_compression_method
                                   (GsfOutfileZip *zip,
                                    GsfZipCompressionMethod method);

## Types and Values

### GsfInfileZip

    typedef struct _GsfInfileZip GsfInfileZip;

### GsfOutfileZip

    typedef struct _GsfOutfileZip GsfOutfileZip;
