.SH NAME
td_thr_tlsbase \- get the base address of a thread's local storage (TLS) block
.SH SYNOPSIS
.LP
.nf
cc [ \fIflag\fR... ] \fIfile\fR...  -lc_db [ \fIlibrary\fR... ]
#include <proc_service.h>
#include <thread_db.h>

    ulong_t \fImoduleid\fR, void psaddr_t *\fIbase\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBtd_thr_tlsbase()\fR function returns the base address of a threads local storage block for the  object specified by \fImoduleid\fR for the thread identified by \fIth_p\fR. The base address is written into *\fIbase\fR.
.sp
.LP
The \fImoduleid\fR is typically obtained by the \fBrd_loadobj_iter()\fR function found in the \fBlibrtld_db\fR(3LIB) library. See \fIScanning Loadable Objects\fR in \fIOracle Solaris 11.3 Linkers and Libraries         Guide\fR.
