Function/Subroutine Documentation

INTEGER function ibfms

(

real*8

R8VAL

)

This function provides a handy way to check whether a real*8 data value returned from a previous call to any of the other BUFRLIB values-reading subroutines contains the current placeholder value for "missing" data.

Parameters

[in]

R8VAL

– real*8: Data value to be tested

Returns

ibfms – integer:

• 0 = R8VAL is not "missing"
• 1 = R8VAL is "missing"

The current placeholder value for "missing" data is always equal to the value XMISS as specified during the most recent call to subroutine setbmiss(), or to a default value of 10E10 if setbmiss() was never called. In either case, a return value of 1 means that the corresponding value was encoded as "missing" (all bits set to 1) within the actual BUFR data subset.

Remarks

• The use of an integer return code allows this function to be called in a logical context from application programs written in C as well as in Fortran.

2009-03-23	J. Ator	Increased value of BDIFD for better test accuracy
2012-10-05	J. Ator	Modified to reflect the fact that the "missing" value is now configurable by users (may be something other than 10E10)
