     9 .SH "DESCRIPTION"

    10 .PP

    11 \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)\&.

    12 .SH "RETURN VALUE"

    13 .PP

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