-.Dt ffi_prep_closure 3
-.Sh NAME
-.Nm ffi_prep_closure
-.Nd Prepare a
-.Nm ffi_closure
-for execution.
-.Sh SYNOPSIS
-.In ffi.h
-.Ft ffi_status
-.Fo ffi_prep_closure
-.Fa "ffi_closure *closure"
-.Fa "ffi_cif *cif"
-.Fa "void (*fun)(ffi_cif*,void*,void**,void*)"
-.Fa "void *user_data"
-.Fc
-.Sh DESCRIPTION
-.Fa closure
-is prepared to execute
-.Fa fun .
-.Fa cif
-contains information describing the data types, sizes and alignments of the
-arguments to and return value from the function that will be called from
-.Fa fun ,
-and must be initialized with
-.Nm ffi_prep_cif
-before it is used with
-.Nm ffi_prep_closure .
-.Fa user_data
-may point to additional data to be used in
-.Fa fun .
-If no additional data is needed,
-.Fa user_data
-may be
-.Nm NULL .
-When
-.Fa closure
-is invoked,
-.Fa fun
-is called with
-.Fa cif ,
-an array of pointers to arguments, a pointer to a return value, and
-.Fa user_data .
-.Pp
-Some architectures do not allow the execution of data by default. In such cases,
-it is necessary to manually alter the permissions of the page that contains
-.Fa closure
-prior to its execution.
-.Sh RETURN VALUES
-Upon successful completion,
-.Nm ffi_prep_closure
-returns
-.Nm FFI_OK .
-If the ABI specified in
-.Fa cif
-does not refer to a valid ABI,
-.Nm FFI_BAD_ABI
-will be returned. Available ABIs are
-defined in
-.Nm <ffi/ppc-ffitarget.h>
-and
-.Nm <ffi/x86-ffitarget.h> .
