CS_HAVE_CMD determines whether an application can resend a previously executed server command. The property is read-only, and CS_TRUE indicates the presence of a resendable command.
Client-Library allows applications to resend some types of commands immediately after the results of the previous execution have been processed.
To resend a command, the application:
Updates values in the command’s parameter source variables (if any). The address of the parameter source variables must have been specified with ct_setparam after the command was initiated with ct_command, ct_cursors, or ct_dynamic.
Calls ct_send to resend the command. ct_send reads the updated parameter values.
Not all command types can be resent. See “Resending commands” on page 584 for more information.
Applications that resend commands may benefit from setting the CS_STICKY_BINDS property to reuse the bindings that were established while processing the results from the original execution of the command. See “Persistent result bindings” for a description of this property.
