I don't know if this has changed on X (!) but my as-of-early-2000
knowledge of Handles says it's important to lock them before
dereferencing them, especially when passing the dereferenced pointer to
a routine which is obviously going to allocate memory :-)

Here's my code for getting the component name (modified a little to
make it simpler):
Handle nameHandle = NewHandle(0);
ComponentDescription cd, theComp;
Component comp;
comp = FindNextComponent(NULL, &cd);
GetComponentInfo(comp, &theComp, nameHandle, NULL, NULL);
NSString *compName = [NSString stringWithCString:*nameHandle
length:GetHandleSize(nameHandle)];
DisposeHandle(nameHandle);

I'm expanding my app into hosting 3rd party AUs and I'm trying to

readable name for the effect (except maybe "CurrentContext" but I want
a context
free name).
I'm now thinking that it's in the ComponentInfo stuff (looking at the
Java examples) but
I'm not sure how to work with this in C (from Components.h):
struct ResourceSpec {
OSType resType; /* 4-byte code */
short resID; /* */
};
typedef struct ResourceSpec ResourceSpec;
struct ComponentResource {
ComponentDescription cd; /* Registration
parameters */
ResourceSpec component; /* resource where
Component code is found */
ResourceSpec componentName; /* name string
resource */
ResourceSpec componentInfo; /* info string
resource */
ResourceSpec componentIcon; /* icon resource */
};
The info I want is in componentName I believe but how to I get it out
of a ResourceSpec.
Thanks,
Robert.
