fdds_prec - fetch field precision

SYNOPSIS

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

integer fdds_prec(bin_tag, field_tag)

integer bin_tag
integer field_tag

DESCRIPTION

fdds_prec returns the precision (effective) associated with the field_tag of a field within a DDS type. The precision is the number of bytes required for the field. It includes all elements of a vector. 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
      integer   RecNum_size
      ...
!     byte size of RecNum field
      tag = fdds_member(bin, 0, 'RecNum')
      RecNum_size = fdds_prec(bin, tag)

SEE ALSO

      fdds_name Fetch field name
      fdds_align Fetch field alignment
      fdds_count Fetch field count
      fdds_genus Fetch field genus
