The environment is modified, not just this particular handle. If some other thread or process has opened the same environment, then this call is ignored. .IP \fIgbytes The number of gibibytes (gibi equals 2^30, giga equals 10^9) to allocate. .IP \fIbytes The number of additional bytes to allocate. .IP \fIncache Ignored in TokuDB. .SH RETURN VALUE .LP Returns zero on success. The following non-zero errors can be returned: .IP \fBEINVAL You passed invalid parameters to this operation. In many cases \fBEINVAL\fR is not a very helpful error code, indicating only that you did something wrong. .SH CONFORMING TO The TokuDB embedded database provides a subset of the functionality of the Berkeley DB. Programs that work with TokuDB probably work with with most versions of Berkeley DB with only recompilation or relinking. The database files are incompatible, however, so to convert from one library to the other you would need to dump the database with one library's tool and load it with the other's. .SH AUTHOR Tokutek, Inc. .SH COPYRIGHT Copyright (c) 2007 Tokutek.
