SDS_READ(3)

NAME

     sds_read sds_write

     -a set of functions to handle FITS file input/output

SYNOPSIS

     #include <soi_sds.h>

     SDS *sds_read(FILE *pointer, int datatype, int filetype)
     int sds_write(SDS *sdsptr, FILE *pointer, int filetype)

DESCRIPTION

     FITS file reader and writer

     sds_read reads from the filepointer provided  and  converts,
     if  necessary  to the new type.  If the type is SDS_ANY then
     the no conversion is performed and the file is read  in  its
     native type.  New with version 0.9, the argument filetype is
     required. Supported filetypes can be found in soi_sds.h.

     sds_write writes out information in the sds to the specified
     stream.

BUGS

     In this release sds_read and sds_write are wrappers  on  the
     lower-level  functions.  Thus, sds_read has all the bugs and
     features of sds_read_fits and sds_convert,  while  sds_write
     has all the bugs and features of sds_write_fits.

     The only filetypes that are  successfully  supported  as  of
     94.06.20 are SDS_FITS and SDS_RAW.
