Function/Subroutine Documentation

subroutine wrdlen

(

void

)

This subroutine figures out some important information about the local machine on which the BUFRLIB software is being run, including the native endianness, the number of bytes in an integer, and whether the machine uses the ASCII or EBCDIC character set.

This subroutine isn't normally called directly by any application program, because it's automatically called internally from within subroutine openbf() during the first time that subroutine is called by any application program. It's also called as needed from within several other subroutines, but it always keeps track of its results as well as whether it has already been called during the life of an application program, and that way if it does end up being called more than once, it will just quietly return without having to recompute all of its results from the first call.
