+.Sh DESCRIPTION
+The
+.Nm ffi_call
+function provides a simple mechanism for invoking a function without
+requiring knowledge of the function's interface at compile time.
+.Fa fn
+is called with the values retrieved from the pointers in the
+.Fa avalue
+array. The return value from
+.Fa fn
+is placed in storage pointed to by
+.Fa rvalue .
+.Fa cif
+contains information describing the data types, sizes and alignments of the
+arguments to and return value from
+.Fa fn ,
+and must be initialized with
+.Nm ffi_prep_cif
+before it is used with
+.Nm ffi_call .
+.Pp
+.Fa rvalue
+must point to storage that is sizeof(ffi_arg) or larger for non-floating point
+types. For smaller-sized return value types, the
+.Nm ffi_arg
+or
+.Nm ffi_sarg
+integral type must be used to hold
+the return value.

+unsigned char
+foo(unsigned int, float);
+
+int

+    // must be passed as ffi_arg or ffi_sarg.
+    ffi_arg result;
+
+    // Specify the data type of each argument. Available types are defined
+    // in <ffi/ffi.h>.
+    arg_types[0] = &ffi_type_uint;
+    arg_types[1] = &ffi_type_float;
+
+    // Prepare the ffi_cif structure.

+    // Invoke the function.
+    ffi_call(&cif, FFI_FN(foo), &result, arg_values);

+.TH ZLIB 3 "15 Jan 2017"
+.SH NAME
+zlib \- compression/decompression library
+.SH SYNOPSIS
+[see
+.I zlib.h
+for full description]
+.SH DESCRIPTION
+The
+.I zlib
+library is a general purpose data compression library.
+The code is thread safe, assuming that the standard library functions
+used are thread safe, such as memory allocation routines.
+It provides in-memory compression and decompression functions,
+including integrity checks of the uncompressed data.
+This version of the library supports only one compression method (deflation)
+but other algorithms may be added later
+with the same stream interface.
+.LP
+Compression can be done in a single step if the buffers are large enough
+or can be done by repeated calls of the compression function.
+In the latter case,
+the application must provide more input and/or consume the output
+(providing more output space) before each call.
+.LP
+The library also supports reading and writing files in
+.IR gzip (1)
+(.gz) format
+with an interface similar to that of stdio.
+.LP
+The library does not install any signal handler.
+The decoder checks the consistency of the compressed data,
+so the library should never crash even in the case of corrupted input.
+.LP
+All functions of the compression library are documented in the file
+.IR zlib.h .
+The distribution source includes examples of use of the library
+in the files
+.I test/example.c
+and
+.IR test/minigzip.c,
+as well as other examples in the
+.IR examples/
+directory.
+.LP
+Changes to this version are documented in the file
+.I ChangeLog
+that accompanies the source.
+.LP
+.I zlib
+is built in to many languages and operating systems, including but not limited to
+Java, Python, .NET, PHP, Perl, Ruby, Swift, and Go.
+.LP
+An experimental package to read and write files in the .zip format,
+written on top of
+.I zlib
+by Gilles Vollant (info@winimage.com),
+is available at:
+.IP
+http://www.winimage.com/zLibDll/minizip.html
+and also in the
+.I contrib/minizip
+directory of the main
+.I zlib
+source distribution.
+.SH "SEE ALSO"
+The
+.I zlib
+web site can be found at:
+.IP
+http://zlib.net/
+.LP
+The data format used by the
+.I zlib
+library is described by RFC
+(Request for Comments) 1950 to 1952 in the files:
+.IP
+http://tools.ietf.org/html/rfc1950 (for the zlib header and trailer format)
+.br
+http://tools.ietf.org/html/rfc1951 (for the deflate compressed data format)
+.br
+http://tools.ietf.org/html/rfc1952 (for the gzip header and trailer format)
+.LP
+Mark Nelson wrote an article about
+.I zlib
+for the Jan. 1997 issue of  Dr. Dobb's Journal;
+a copy of the article is available at:

+.SH "REPORTING PROBLEMS"
+Before reporting a problem,
+please check the
+.I zlib
+web site to verify that you have the latest version of
+.IR zlib ;
+otherwise,
+obtain the latest version and see if the problem still exists.
+Please read the
+.I zlib
+FAQ at:
+.IP
+http://zlib.net/zlib_faq.html
+.LP
+before asking for help.
