.TH SETUPSHARES 3 SHARE
.SH NAME
setupshares \- set kernel shares for a user
.SH SYNOPSIS
.B setupshares(uid, efp)
.br
.B int uid;
.br
.B void (*efp)();
.SH DESCRIPTION
This library routine sets up a kernel shares structure
for the user represented by
.IR uid .
It extracts the share details for the user from the shares data-base,
decays the usage figure up to the current time,
and uses
.IR setlimits (3)
to install the shares in the kernel.
.PP
If the system is out of
.I lnode
structures, then the structure for the default user ``other'' is used.
If this also fails, then the structure for the super-user is used.
.PP
If there are any errors, and the second argument is non-NULL,
the function will be called with a
.IR printf (3)
format string and at most one extra argument.
A non-zero result is returned for un-recoverable errors.
Otherwise,
.I setupshares
returns \fB0\fP.
.PP
This routine is safe to use on systems
where the share scheduler has not been installed,
or is inactive.
.SH DIAGNOSTICS
.I Setupshares
returns a non-zero result if
.IR setlimits (3)
returns an error other than
.SM ETOOMANYU.
The optional error routine is called if
.IR setlimits (3)
returns any error,
or if no shares have been allocated to the user.
