NAME

ffi_read() - read a typed scalar from a buffer

SYNOPSIS

mixed ffi_read( buffer mem, int offset, int type_code );

DESCRIPTION

Reads the scalar of type `type_code` (a code from <ffi.h>) stored at
byte `offset` within `mem`, returning an int for integer/pointer
types or a float for FFI_FLOAT/FFI_DOUBLE. Combine with
ffi_struct_layout() to read C struct fields symbolically.
