ZCOM C I/F Library Routines
ZCONFIG (3X)
| This is the node number of the remote (or local) ZCOM |
| system where the configuration is to take place. If zero |
| is specified, it is the local system. Note that the node |
| parameter must specify the local system with this |
| release (except for the Port Configuration functions) |
cdata | Configuration data. |
| This points to a data structure containing all the |
| information necessary for the configuration. See below |
| for a description of this structure. |
rdata
(Return Param) Response data.
This points to a data structure containing the returned configuration response data. It is returned with valid data only when it is an immediate configuration (mode ZcDSC_IMMEDIATE) and zconfig returns with zero (i.e. no error). See the following for a description of this structure.
Configuration Data The configuration data structure consists of a header and a “union” data portion for configuration information
