.SH NAME
typedef handle_t \- The handle_t type represents a single atomic update being performed by some process.
.SH SYNOPSIS

.nf
typedef handle_t;
.fi
.SH "DESCRIPTION"
.PP
.PP
All filesystem modifications made by the process go
through this handle.  Recursive operations (such as quota operations)
are gathered into a single update.
.PP
The buffer credits field is used to account for journaled buffers
being modified by the running process.  To ensure that there is
enough log space for all outstanding operations, we need to limit the
number of outstanding buffers possible at any time.  When the
operation completes, any buffer credits not used are credited back to
the transaction, so that at all times we know how many buffers the
outstanding updates on a transaction might possibly touch. 
.PP
This is an opaque datatype.
