INTEGER function ireadmt | ( | LUN | ) |
This function checks the most recent BUFR message that was read via a call to one of the message-reading subroutines and determines whether the appropriate corresponding BUFR master tables have already been read into internal memory.
If not, then it opens the appropriate master BUFR tables on the local file system and then reads the contents into internal memory, clearing any previous master BUFR table information that may have previously been stored there.
[in] | LUN | – integer: Internal I/O stream index associated with BUFR file |
Information about the location of master BUFR tables on the local file system is obtained from the most recent call to subroutine mtinfo(), or else from subroutine bfrini() if subroutine mtinfo() was never called, and in which case Fortran logical unit numbers 98 and 99 will be used by this function for opening and reading master BUFR table files.
