/************************************************************************
f77_wrap1.c and f77_wrap2.c have now been split into 4 files to
prevent compile-time memory errors (from expansion of compiler commands).
f77_wrap1.c was split into f77_wrap1.c and f77_wrap3.c, and
f77_wrap2.c was split into f77_wrap2.c and f77_wrap4.c:
f77_wrap1.c contains routines operating on whole files and some
utility routines.
f77_wrap2.c contains routines operating on primary array, image,
or column elements.
f77_wrap3.c contains routines operating on headers & keywords.
f77_wrap4.c contains miscellaneous routines.
Peter's original comments:
Together, f77_wrap1.c and f77_wrap2.c contain C wrappers for all
the CFITSIO routines prototyped in fitsio.h, except for the
generic datatype routines and features not supported in fortran
(eg, unsigned integers), a few routines prototyped in fitsio2.h,
which only a handful of FTOOLS use, plus a few obsolete FITSIO
routines not present in CFITSIO. This file allows Fortran code
to use the CFITSIO library instead of the FITSIO library without
modification. It also gives access to new routines not present
in FITSIO. Fortran FTOOLS must continue using the old routine
names from FITSIO (ie, ftxxxx), but most of the C-wrappers simply
redirect those calls to the corresponding CFITSIO routines (ie,
ffxxxx), with appropriate parameter massaging where necessary.
The main exception are read/write routines ending in j (ie, long
data) which get redirected to C routines ending in k (ie, int
data). This is more consistent with the default integer type in
Fortran. f77_wrap1.c primarily holds routines operating on whole
files and extension headers. f77_wrap2.c handle routines which
read and write the data portion, plus miscellaneous extra routines.
