    printf("Zip eocd app note version: %d\n", (version_madeby & 0xFF));
}
```

### mz_zip_set_version_madeby

Sets the zip file's version information. The application that original wrote the zip file would have set this value to indicate what operating system and version of the zip specification that was used when making it. This version is stored in the end of central directory record; there is another similar _version_madeby_ stored for each zip entry.

**Arguments**
|Type|Name|Description|

mz_zip_set_version_madeby(zip_handle, custom_version_madeby);
```

### mz_zip_set_recover

Sets the ability to recover/repair the central directory. When the central directory is damaged or incorrectly written, it may be possible to recover it by reading the local file headers. Reading all of the local file headers can be a disk intensive operation and take significant time for large files.

**Arguments**
|Type|Name|Description|
|-|-|-|
|void *|handle|_mz_zip_ instance|
|uint8_t|recover|Set to 1 to enable central directory recover, set to 0 otherwise.|

**Return**
|Type|Description|

**Example**
```
void *zip_handle = mz_zip_create();

    printf("Central directory recovery enabled if necessary\n");
```

### mz_zip_set_data_descriptor

Sets wehther or not zip file entries will be written with a data descriptor. When data descriptor writing is enabled it will zero out the crc32, compressed size, and uncompressed size in the local header. By default data descriptor writing is enabled and disabling it will cause zip file entry writing to seek backwards to fill in these values after writing the compressed data.

**Arguments**
|Type|Name|Description|
|-|-|-|
|void *|handle|_mz_zip_ instance|
|uint8_t|data_descriptor|Set to 1 to enable data descriptor writing, set to 0 otherwise.|

**Return**
|Type|Description|
|-|-|
|int32_t|[MZ_ERROR](mz_error.md) code, MZ_OK if successful|

**Example**
```
void *zip_handle = mz_zip_create();
// Enable data descriptor writing for zip entries
if (mz_zip_set_data_descriptor(zip_handle, 0) == MZ_OK)
    printf("Local file header entries will be written with crc32 and sizes\n");
```

### mz_zip_get_stream

Gets the _mz_stream_ handle used in the call to _mz_zip_open_.

**Arguments**
|Type|Name|Description|
|-|-|-|
|void *|handle|_mz_zip_ instance|
|void **|stream|Pointer to _mz_stream_ instance|

**Return**
|Type|Description|
|-|-|
|int32_t|[MZ_ERROR](mz_error.md) code, MZ_OK if successful|

**Example**
```
void *zip_handle = mz_zip_create();
if (mz_zip_open(zip_handle, stream_handle, MZ_OPEN_MODE_READ) == MZ_OK) {
    void *stream2_handle = NULL;
    mz_zip_get_stream(zip_handle, &stream2_handle);
    assert(stream_handle == stream2_handle);
}
```

### mz_zip_set_cd_stream

Sets the stream to use for reading the central directory.

The central directory stream might not be the same as the stream used for reading local file entries. In the case of split disks, they are different and handles to both are open at the same time to keep from opening and closing streams while reading entries.

This function is used when encrypting the central directory, it is decrypted and extracted into a memory stream, and that memory stream is set as the central directory stream.

**Arguments**
|Type|Name|Description|
|-|-|-|
|void *|handle|_mz_zip_ instance|
|int64_t|cd_start_pos|Start position of central directory in the stream|
|void *|cd_stream|_mz_stream_ instance to use for reading central directory. The cd_stream must be valid as long as it is being used by _mz_zip_.|

**Return**
|Type|Description|
|-|-|
|int32_t|[MZ_ERROR](mz_error.md) code, MZ_OK if successful|

**Example**
```
void *cd_mem_stream = mz_stream_mem_create();
// TODO: Write central directory to memory stream
mz_zip_set_cd_stream(zip_handle, 0, cd_mem_stream);
```

### mz_zip_get_cd_mem_stream

Gets the stream used to store the central directory in memory for writing.

When writing to a zip file the central directory is written to this memory stream and written after all entries are written. When a zip file is opened for appending, the central directory is stored in memory while the appending new zip entries.

**Arguments**
|Type|Name|Description|
|-|-|-|
|void *|handle|_mz_zip_ instance|
|void *|cd_stream|Pointer to _mz_stream_ instance that is used for writing the central directory.|

**Return**
|Type|Description|
|-|-|
|int32_t|[MZ_ERROR](mz_error.md) code, MZ_OK if successful|

**Example**
```
// TODO: Open zip file for writing and write at least one entry
void *cd_mem_stream = NULL;
if (mz_zip_get_cd_mem_stream(zip_handle, &cd_mem_stream) == MZ_OK) {
    int64_t org_position = mz_stream_tell(cd_mem_stream);
    mz_stream_seek(cd_mem_stream, 0, MZ_SEEK_END);
    int64_t cd_length = mz_stream_tell(cd_mem_stream);
    mz_stream_seek(cd_mem_stream, org_position, MZ_SEEK_SET);
    printf("Length of central directory to write: %d\n", cd_length);
}
```

```
// TODO: Load central directory into memory stream
mz_zip_set_cd_stream(zip_handle, 0, cd_mem_stream);
mz_zip_set_number_entry(zip_handle, 10);
```

**Example**
```
err = mz_zip_goto_first_entry(zip_handle);
if (err == MZ_OK)
    err = mz_zip_entry_read_open(zip_handle, 0, NULL);
if (err == MZ_OK)
    printf("Zip entry open for reading\n");
```

### mz_zip_entry_read

Reads bytes from the current entry in the zip file. The data returned in the buffer will be the decrypted and decompressed bytes unless the entry is opened for raw data reading.

**Example**
```
int32_t bytes_read;
int32_t err = MZ_OK;
char buf[4096];
do {
    bytes_read = mz_zip_entry_read(zip_handle, buf, sizeof(buf));
    if (bytes_read < 0) {
        err = bytes_read;
    }
    // TODO: Do something with buf bytes
} while (err == MZ_OK && bytes_read > 0);
```

### mz_zip_entry_read_close

Closes the current entry in the zip file for reading and returns the data descriptor values if the zip entry has the data descriptor flag set. If the data descriptor values are not necessary, _mz_zip_entry_close_ can be used instead.

    printf("Unix -> NTFS: %lld -> %lld\n", unix_time, ntfs_time);
}
```

## Path

### mz_zip_path_compare

Compare two paths without regard to slashes. Some zip files have paths with unix slashes and some zip files have paths containing windows slashes.

**Arguments**
|Type|Name|Description|
|-|-|-|
|const char *|path1|First path to compare|
|const char *|path2|Second path to compare|
|uint8_t|ignore_case|Ignore case if 1.|

**Return**
|Type|Description|
|-|-|
|int32_t|[MZ_ERROR](mz_error.md) code, MZ_OK if successful.|

**Example**
```
const char *search_path = "folder1/test1.txt";
mz_zip_file *file_info = NULL;
if (mz_zip_entry_get_info(zip_handle, &file_info) == MZ_OK) {
    if (mz_zip_path_compare(file_info->filename, search_path, 0) == MZ_OK)
        printf("Found %s\n", search_path);
    else
        printf("Not found %s\n", search_path);
}
```

## String

### mz_zip_get_compression_method_string

Gets a string representing the compression method.

**Arguments**
|Type|Name|Description|
|-|-|-|
|int32_t|compression_method|Compression method index|

**Return**
|Type|Description|
|-|-|
|const char *|String representing compression method or "?" if not found|

**Example**
```
const char *method = mz_zip_get_compression_method_string(MZ_ZIP_COMPRESS_METHOD_LZMA);
printf("Compression method %s\n", method);
```
