mdbm_nextkey

NAME

mdbm_nextkey - Get the "next" key from a mdbm database

SYNOPSIS

string mdbm_nextkey(int handle, string key)

DESCRIPTION

Returns the "next" key after the given key in an mdbm database has previously been opened by a call to the mdbm_open() kfun. The "handle" returned by that kfun is used as an argument to this kfun.

Zero is returned to indicate failure.

NOTES

The order of keys in a database isn't based on anything interesting.

Deleting a key changes the order of the keys in a database, so be careful of such changes in the midst of firstkey/nextkey loops over the database as such a change may mean that all keys are not visited in the loop.
