CFIO_GetCharAtt Subroutine

public subroutine CFIO_GetCharAtt(fid, name, count, buf, rc)

CFIO_GetCharAtt – Read a user-defined character attribute

This routine allows the user to read a character attribute from an open CFIO file.

History

  • 1998.07.30 Lucchesi Initial interface design.
  • 1998.07.30 Lucchesi Initial coding.
  • 1998.09.29 Lucchesi Changed error handling.

Arguments

Type IntentOptional Attributes Name
integer :: fid

File handle
character(len=*) :: name

Name of attribute
integer :: count

On input: Number of items in attribute On output: If rc = -1, count will contain the correct number of attributes
character(len=1) :: buf(count)

Buffer with character values
integer :: rc

Error return code: rc = 0 all is well rc = -1 invalid count rc = -2 type mismatch

NetCDF Errors

rc = -36 error from NF90_PUT_ATT (global attribute) rc = -51 error from NF90_GET_ATT (global attribute)
