mdbm_reorganize

NAME

mdbm_reorganize - Reorganize a mdbm database file.

SYNOPSIS

int mdbm_reorganize(int handle)

DESCRIPTION

In general the file associated with a mdbm database will not shrink after key/value deletions (although the space will be reused for future insertions). After a large number of deletions this kfun may be called to shrink the size of that associated file. The database must have been previously 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, one to indicate success.

NOTES

The execution of this function is expensive and it should be used sparingly.

This kfun is only available is the mdbm package has been compiled to use gdbm rather than ndbm databases.
