error reporting is desired.
CONST char *resourceName (in) Name of TEXT resource to
source, NULL if number should
be used.
int resourceNumber (in) Resource id of source.
CONST char *fileName (in) Name of file to process. NULL
if application resource.
Handle resource (in) Handle to TEXT resource.
long resourceType (in) Type of resource to load.
CONST char *resFileRef (in) Registered resource file ref‐
erence, NULL if searching all
open resource files.
int *releaseIt (out) Should we release this
resource when done.
int newOSType (in) Int used to initialize the
new object or set the
object's value.
Tcl_Obj *objPtr (in) Object whose internal repre‐
sentation is to be set or
retrieved.
osTypePtr out Place to store the resulting
integer.
Tcl_MacConvertEventPtr procPtr(in)
Reference to the new function

_________________________________________________________________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 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.
Tcl_MacConvertTextResource 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 mem‐
ory.
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 applica‐
tion. This function will be passed all incoming Mac events. This func‐
tion usually controls the console or some other entity like Tk.
RESOURCE TYPES
Resource types are 4-byte values used by the macintosh resource facil‐
ity 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 charac‐
ters such a type can be interpreted as a 4 character string too.
