\fBUint32 \fBSDL_WasInit\fP\fR(\fBUint32 flags\fR);

.SH "DESCRIPTION"

.PP

\fBSDL_WasInit\fP allows you to see which SDL subsytems have been \fIinitialized\fR\&. \fBflags\fR is a bitwise OR\&'d combination of the subsystems you wish to check (see \fI\fBSDL_Init\fP\fR for a list of subsystem flags)\&.

.SH "RETURN VALUE"

.PP

\fBSDL_WasInit\fP returns a bitwised OR\&'d combination of the initialized subsystems\&.
