Hi,
with some minor changes the pthreads CVS snapshot from
today (2006-11-28 PTW32_VERSION 2,8,0,0) compiles with
Visual C++ 8.0.5 2005 (on a XP)
for the target
Windows CE 4.2, Smartphone 2003 with ARM4 processor.
My multi threaded application seem to run fine, but
it keeps getting strange return codes for
pthread_cond_destroy()
pthread_mutex_destroy()
those calls return 16 (which is EBUSY) in need_errno.h.
I ignore it and my applications continues as expected.
Most probably this (my) hack is the reason:
What do i have to return in pthread_cancel.c instead of FpExc??

(Context is defined in my winnt.h)
Here it is: C:\Program Files\Microsoft Visual Studio
8\SmartDevices\SDK\Smartphone2003\Include\winnt.h
...
typedef struct _CONTEXT {
//
// The flags values within this flag control the contents of
// a CONTEXT record.
//
// If the context record is used as an input parameter, then
// for each portion of the context record controlled by a flag
// whose value is set, it is assumed that that portion of the

//
// If the context record is used as an IN OUT parameter to capture

// context corresponding to set flags will be returned.
//
// The context record is never used as an OUT only parameter.

ULONG ContextFlags;

} CONTEXT;
....
What is the role of process.h (as i have disabled it, see patch below)?
In errno.c there are pthread_self () returns pthread_t
which is sometimes a pointer on a big struct, whereas in
my case it ended up to
typedef struct {
void * p; /* Pointer to actual object */
unsigned int x; /* Extra information - reuse count etc */
} ptw32_handle_t;
How can i track this down?
thank you
Marcel
