PrfReset - Remarks

This function causes the workstation to use different profiles. When the workstation is initialized, the names of the user and system profiles are taken from the PROTSHELL statement specified in CONFIG.SYS. PrfReset allows the profiles to be changed during operation of the workstation, for example by a logon application controlling multiple consecutive users of the system.

After the PrfReset function completes, the system has a new set of preferences (for example screen colors), a new start-up list, and new spooler parameters.

The PrfReset function broadcasts the PL_ALTERED message, which must be processed by all applications that read their default settings from the user or system profiles.

Note: This will only change the default system values in the ini file. It is up to the applications to read the new default settings and reset them to their new values.

For example, consider logon applications. On receipt of a PL_ALTERED message, they should carry out the following:

• Read the new color settings from the new profiles, and set the new screen colors (and palettes) which should be refreshed.

• Set the country information, for example the date and time format, which is read from the new profiles.

• Other preferences, for example, those that affect the operations of the alarm and the mouse, should also update with the new settings held in the new profiles.

This function requires the existence of a message queue.
