o32FFT(3F)o32FFT(3F)NAMEo32FFT - o32 vs. n32/64 FFT library differences
DESCRIPTION
The Development Magic (-o32) FFT library differs from the -n32/-64 FFT
library. The -o32 FFT library contains only a subset of the routines in
the -n32/-64 library.
The -o32 FFT library contains the following routines:
sfft1di dfft1di cfft1di zfft1di
sfft1d dfft1d cfft1d zfft1d
sfft2di dfft2di cfft2di zfft2di
sfft2d dfft2d cfft2d zfft2d
sfft3di dfft3di cfft3di zfft3di
sfft3d dfft3d cfft3d zfft3d
sfft1dui dfft1dui csfft1d zdfft1d
sfft1du dfft1du
sfft2dui dfft2dui
sfft2du dfft2du
sfft3dui dfft3dui
sfft3du dfft3du
However, only the unpacked s* and d* routines are documented. From the
complib 1.0 FFT introduction man page:
The routines
sfft_di, sfft_d, sprod_d,
dfft_di, dfft_d, dprod_d,
are packed versions of
sfft_dui, sfft_du, sprod_du,
dfft_dui, dfft_du, dprod_du,
and are available for compatibility with previous
versions of libfft. It is advisable to use the
nonpacked versions (e.g. sfft1dui should be used
instead of sfft1di).
csfft1d and zdfft1d are also in the library for
compatibility with previous versions of libfft.
The above packed routines are not documented.
The -n32/-64 FFT library contains all of the the routines in the -o32 FFT
library and also includes:
cfft1di zfft1di
cfft1d zfft1d

There are no plans to provide the full functionality of the -n32/-64
library FFT library for -o32.
