NAME
cbsync - synchronize cbase
SYNOPSIS
#include <cbase.h>
int cbsync(cbp)
cbase_t *cbp;
DESCRIPTION
The cbsync function causes any buffered data for the named cbase to
be written out, both for the record and the key files. The cbase
remains open and the buffer contents remain intact.
cbsync will fail if one or more of the following is true:
[EINVAL] cbp is not a valid cbase pointer.
[EINVAL] cbp is not open.
SEE ALSO
cbclose, cblock.
DIAGNOSTICS
Upon successful completion, a value of 0 is returned. Otherwise, a
value of -1 is returned, and errno set to indicate the error.
