.SH PARAMETERS
.TP 20
\fIExpr\fP
Expression.
.TP
\fIMode\fP
The returned support's mode.
.SH DESCRIPTION
\fBgetablexprsupport\fP gives the support of \fIExpr\fP. if \fIMode\fP
is ABL_SUPPORT_CHAIN the support is returned using \fIchain_list\fP
else it is returned using \fIptype_list\fP. The support must be freed
using the \fIfreechain\fP or \fIfreeptype\fP functions.

.SH RETURN VALUE
\fBgetablexprsupport\fP returns a pointer to a \fIchain_list\fP or
a \fIptype_list\fP.
