0011 SYNOPSIS

0013
0014 #include <ubf.h>
0015
0016 int Bojoin(UBFH *'dest', UBFH *'src');

0020 DESCRIPTION
0021 -----------
0022 Bojoin function is similar to Bjoin function.
0023 Outer join function updates destination buffer in 'dest' with source buffer 'src'
0024 values based on matching fields and occurrence. Function will update existing
0025 fields from source buffer to destination with matching occurrences. If field
0026 does not exist or occurrence does not exists, then field/occurrence is not removed
0027 from destination buffer. By comparing to *Bupdate(3)*, this function updates only
0028 matched fields, and does not add any missing as it is done by *Bupdate(3)*. By
0029 comparing to *Bjoin(3)*, *Bjoin(3)* will remove not matched fields from 'dest',
0030 but *Bojoin()* will leave dest fields non deleted.

0033 RETURN VALUE

0036 to indicate the error.
