The prowait( ) function causes your application to suspend execution until a specified interval timer, set by the proevt( ) function, expires. Use prowait( ) only in special circumstances; signals and interrupts do not interrupt this function:
Syntax
void
prowait ( pflag )
char *pflag;
pflag
This input parameter points to a timer flag previously passed to proevt( ) in order to start the specified time interval. This flag specifies one of many interval timers you can set with proevt( ).
Note: This function applies only to UNIX systems. For more information on using interval timers, see HostLanguage Call Interface.
