+.SH DESCRIPTION
+.sp
+.LP
+The \fBpool_dynamic_location()\fR function returns the location used by the
+pools framework to store the dynamic configuration.
+.sp
+.LP
+The \fBpool_static_location()\fR function returns the location used by the
+pools framework to store the default configuration used for pools framework
+instantiation.
+.sp
+.LP
+The \fBpool_version()\fR function can be used to inquire about the version
+number of the library by specifying \fBPOOL_VER_NONE\fR. The current (most
+capable) version is \fBPOOL_VER_CURRENT\fR. The user can set the version used
+by the library by specifying the required version number. If this is not
+possible, the version returned will be \fBPOOL_VER_NONE\fR.
+.sp
+.LP
+The \fBpool_get_status()\fR function retrieves the current state of the pools
+facility. If state is non-null, then on successful completion the state of the
+pools facility is stored in the location pointed to by state.
+.sp
+.LP
+The \fBpool_set_status()\fR function modifies the current state of the pools
+facility. On successful completion the state of the pools facility is changed
+to match the value supplied in state. Only two values are valid for state,
+\fBPOOL_DISABLED\fR and \fBPOOL_ENABLED\fR, both of which are defined in
+<\fBpool.h\fR>.
+.sp
+.LP
+The \fBpool_resource_type_list()\fR function enumerates the resource types
+supported by the pools framework on this platform. If \fInumres\fR and
+\fIreslist\fR are both non-null, \fIreslist\fR points to a buffer where a list
+of resource types in the system is to be stored, and \fInumres\fR points to the
+maximum number of resource types the buffer can hold. On successful completion,
+the list of resource types up to the maximum buffer size is stored in the
+buffer pointed to by \fIreslist\fR.
+.SH RETURN VALUES
+.sp
+.LP
+The \fBpool_dynamic_location()\fR function returns the location used by the
+pools framework to store the dynamic configuration.
+.sp
+.LP
+The \fBpool_static_location()\fR function returns the location used by the
+pools framework to store the default configuration used for pools framework
+instantiation.
+.sp
+.LP
+The \fBpool_version()\fR function returns the version number of the library or
+\fBPOOL_VER_NONE\fR.
+.sp
+.LP
+Upon successful completion, \fBpool_get_status()\fR, \fBpool_set_status()\fR,
+and \fBpool_resource_type_list()\fR all return 0. Otherwise, \(mi1 is returned
+and \fBpool_error\fR(3POOL) returns the pool specific error.
+.SH ERRORS
+.sp
+.LP
+No errors are defined for \fBpool_dynamic_location()\fR,
+\fBpool_static_location()\fR, and \fBpool_version()\fR.
