fdds_genus - fetch field genus type

SYNOPSIS

#include <fdds.h> (fixed-format sources)
#include <f90dds.h> (free-format sources)

integer fdds_genus(field_genus, bin_tag, field_tag)

character(DEFNNAME_MAX) field_genus
integer bin_tag
integer field_tag

DESCRIPTION

fdds_genus returns the generic data type (genus) associated with the field_tag in the variable, field_genus. The types include void, bytes, char, unsigned, integer, float, complex and frame. The returned value is 0 on normal return. A value of -1 is returned on any error.

INPUT

bin_tag is a binary tag, previously obtained from fdds_open. It specifies a particular binary stream.

field_tag is the tag of the field for which the information is desired.

EXAMPLE

      integer   bin, tag, ier
      character*(DEFNNAME_MAX) name, genus
      ...
!     scan trace headers
      tag = fdds_member(bin, 0, ' ')
      dowhile (tag.ne.0)
         ier = fdds_name(name, bin, tag)
         ier = fdds_genus(genus, bin, tag)
         ...
         tag = fdds_next(bin,tag)
      enddo
