int dbm_error(DBM *db);The dbm_error() function returns the error condition of the database. The argument db is a handle to a database previously obtained by dbm_open().
Special behavior for z/OS® UNIX Services: In a multithreaded environment, the database error indicator is global to all threads using the database handle. Thus, the database error indicator may be set as a result of a database operation by another thread.
dbm_error() returns 0 if the error condition is not set.
dbm_error() returns nonzero if the error condition is set.
