Creates a scalar handler calling netsnmp_create_handler with a handler name defaulted to 'scalar' and access method, netsnmp_scalar_helper_handler.

.SS "int netsnmp_register_read_only_scalar (\fBnetsnmp_handler_registration\fP * reginfo)"
.PP
This function registers a read only scalar helper handler. 
.PP
This function is very similar to netsnmp_register_scalar the only addition is that the 'read_only' handler is injected into the handler chain prior to injecting the serialize handler and registering reginfo.
.PP
\fBParameters:\fP
.RS 4
\fIreginfo\fP a handler registration structure which could get created using netsnmp_create_handler_registration. Used to register a read only scalar helper handler.
.RE
.PP
\fBReturns:\fP
.RS 4
MIB_REGISTERED_OK is returned if the registration was a success. Failures are MIB_REGISTRATION_FAILURE and MIB_DUPLICATE_REGISTRATION.

.SS "int netsnmp_register_scalar (\fBnetsnmp_handler_registration\fP * reginfo)"
.PP
This function registers a scalar helper handler. 
.PP
The registered OID, reginfo->rootoid, space is extended for the instance subid using realloc() but the reginfo->rootoid_len length is not extended just yet. .This function subsequently injects the instance, scalar, and serialize helper handlers before actually registering reginfo.
.PP
Each handler is injected/pushed to the top of the handler chain list and will be processed last in first out, LIFO.
