An installed copy of libffi is now required for building _ctypes on
any platform but OSX and Windows.

-.Dt ffi_call 3
-.Sh NAME
-.Nm ffi_call
-.Nd Invoke a foreign function.
-.Sh SYNOPSIS
-.In ffi.h
-.Ft void
-.Fo ffi_call
-.Fa "ffi_cif *cif"
-.Fa "void (*fn)(void)"
-.Fa "void *rvalue"
-.Fa "void **avalue"
-.Fc
-.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.
-.Sh EXAMPLES
-.Bd -literal
-#include <ffi.h>
-#include <stdio.h>
-
-unsigned char
-foo(unsigned int, float);
-
-int
-main(int argc, const char **argv)
-{
-    ffi_cif cif;
-    ffi_type *arg_types[2];
-    void *arg_values[2];
-    ffi_status status;
-
-    // Because the return value from foo() is smaller than sizeof(long), it
-    // 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.
-    if ((status = ffi_prep_cif(&cif, FFI_DEFAULT_ABI,
-        2, &ffi_type_uint8, arg_types)) != FFI_OK)
-    {
-        // Handle the ffi_status error.
-    }
-
-    // Specify the values of each argument.
-    unsigned int arg1 = 42;
-    float arg2 = 5.1;
-
-    arg_values[0] = &arg1;
-    arg_values[1] = &arg2;
-
-    // Invoke the function.
-    ffi_call(&cif, FFI_FN(foo), &result, arg_values);
-
-    // The ffi_arg 'result' now contains the unsigned char returned from foo(),
-    // which can be accessed by a typecast.
-    printf("result is %hhu", (unsigned char)result);
-
-    return 0;

-
-// The target function.
-unsigned char
-foo(unsigned int x, float y)

-    unsigned char result = x - y;
