The util functions allow you to control the appearance and logic within the pvbrowser window. These functions are included in the libraries listed in the project file. They are platform independent. Thus you don't have to worry about on which operating system your pvserver may run. Currently Linux/Unix, Windows and OpenVMS are supported for pvserver programming.
The util functions include the "PARAM *p" describing the connection to pvbrowser client. "p->s" is the socket used for communication especially.
Following is the "id" of the widget that is listed in the enum on top of mask<X> generated form mask<X>.ui .
The trailing parameters are for the individual functions.
Calling these functions will send ASCII text to pvbrowser client. The pvbrowser client will interpret the text and call Qt methods accordingly.
