Session parameters

The parameter-information descriptor, MI_PARAMETER_INFO, allows you to set the following session parameters for the client LIBMI application:

• Disables invocation of callbacks
• Enables checking of pointers

Unlike most DataBlade® API structures, the parameter-information descriptor is not an opaque C data structure. To access session-parameter information, you must directly access the fields of a parameter-information descriptor that you allocate. The following table shows the fields in the MI_PARAMETER_INFO structure.

Table 1. Fields in the parameter-information descriptor

Field	Data type	Description
callbacks_enabled	mi_integer	Indicates whether callbacks are enabled: A value of 1 indicates that callbacks are enabled. A value of 0 indicates that callbacks are disabled.
pointer_checks_enabled	mi_integer	Indicates whether pointers (such as MI_ROW pointers) that the client LIBMI application passes to the database server are checked to ensure that they are within the heap space of the process: A value of 1 indicates that pointers are checked. A value of 0 indicates that pointers are not checked.

Before you establish a connection, you can determine which of the following session parameters to use:

• The system-default session parameters
• Default session parameters that you specify
