# zzip\_file\_read(3)

read data.

## NAME

zzip\_file\_read -  read data.

## SYNOPSIS

```
#include <zzip/lib.h>

zzip_ssize_t
zzip_file_read(ZZIP_FILE* fp, void* buf, zzip_size_t len)
```

## DESCRIPTION

 The *zzip\_file\_read* function reads data from zip-contained file.

 This fuction works like *[read(2)](/read/2.md)* and will fill the given buffer with bytes from the opened file. It will return the number of bytes read, so if the *EOF* is encountered you will be prompted with the number of bytes actually read.

 This is the routines that needs the *buf32k* buffer, and it would have need for much more polishing but it does already work quite well.

 Note: the 32K buffer is rather big. The original inflate-algorithm required just that but the latest zlib would work just fine with a smaller buffer.
