ARGUMENTS¶
- Tcl_Interp *interp (in)

- Name of TEXT resource to source, NULL if number should be
used.

- Handle to TEXT resource.
- long resourceType (in)
- Type of resource to load.
- CONST char *resFileRef (in)
- Registered resource file reference, 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 representation is to be set or
retrieved.
-
osTypePtr out

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 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.
