ffi_alloc

NAME

ffi_alloc() - allocate a native memory block as a buffer

SYNOPSIS

buffer ffi_alloc( int nbytes );

DESCRIPTION

Returns a zeroed buffer of `nbytes` bytes whose storage is the native
memory block itself, suitable for structs, out-parameters, and
pointer arguments to ffi_call(). The block is reference-counted like
any buffer and freed by the GC; ffi_free() releases it early.
