INTRODUCTION

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

DESCRIPTION

Tcl_MacEvalResource extends the source command to Macin tosh 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.

Tcl_MacConvertTextResource converts a TEXT resource into a Tcl suit''ltos``0',.and appends ahNULL.uThedcalleryhascon verts ``
the responsibility for freeing the memory.

Tcl_MacFindResource provides a higher level interface for loading resources. It is used by resource read.

Tcl_NewOSTypeObj is used to create a new resource name type object. The object type is "ostype".

Tcl_SetOSTypeObj modifies an object to be a resource type and to have the specified long value.

Tcl_GetOSTypeFromObj 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.

Tcl_MacSetEventProc 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.

RESOURCE TYPES

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.
