CFIO_PutRealAtt Subroutine

public subroutine CFIO_PutRealAtt(fid, name, count, buf, prec, rc)

CFIO_PutRealAtt – Write a user-defined real attribute

This routine allows the user to define a real attribute in an open CFIO file.

History

  • 1998.07.30 Lucchesi Initial interface design.
  • 1998.07.30 Lucchesi Initial coding.
  • 1998.09.24 Lucchesi Changed error handling.
  • 1998.09.28 Lucchesi Added support for multiple precisions

Arguments

Type IntentOptional Attributes Name
integer :: fid

File handle
character(len=*) :: name

Name of attribute
integer :: count

Number of integers to write
real :: buf(count)

Buffer with real values
integer :: prec

Desired precision of attribute value: 0 = 32 bit 1 = 64 bit
integer :: rc

Error return code: rc = 0 all is well rc = -12 error determining default precision

NetCDF Errors

rc = -36 error from NF90_PUT_ATT (global attribute) rc = -55 error from NF90_REDEF (enter define mode) rc = -56 error from NF90_ENDDEF (exit define mode)
