.SH INTRODUCTION
.PP
The described routines are used to implement the Macintosh specific
\fBresource\fR command and the Mac specific notifier.. They manipulate
or use Macintosh resources and provide administration for open
resource file references.

.SH DESCRIPTION
.PP
\fBTcl_MacEvalResource\fR extends the \fBsource\fR command to
Macintosh resources.  It sources Tcl code from a Text resource.
Currently only sources the resource by name, file IDs may be supported
at a later date.
.PP
\fBTcl_MacConvertTextResource\fR converts a TEXT resource into a Tcl
suitable string. It mallocs the returned memory, converts ``\\r'' to
``\\n'', and appends a null. The caller has the responsibility for
freeing the memory.
.PP
\fBTcl_MacFindResource\fR provides a higher level interface for
loading resources. It is used by \fBresource read\fR.
.PP
\fBTcl_NewOSTypeObj\fR is used to create a new resource name type
object. The object type is "ostype".
.PP
\fBTcl_SetOSTypeObj\fR modifies an object to be a resource type and to
have the specified long value.
.PP
\fBTcl_GetOSTypeFromObj\fR attempts to return an int from the Tcl
object "objPtr". If the object is not already an int, an attempt will
be made to convert it to one.
.PP
\fBTcl_MacSetEventProc\fR sets the event handling procedure for the
application. This function will be passed all incoming Mac events.
This function usually controls the console or some other entity like
Tk.

.SH RESOURCE TYPES
.PP
Resource types are 4-byte values used by the macintosh resource
facility to tag parts of the resource fork in a file so that the OS
knows how to handle them. As all 4 bytes are restricted to printable
characters such a type can be interpreted as a 4 character string too.

.SH KEYWORDS
macintosh, mac, resource, notifier
