Hi,
I have a very simple program. It basically tries to open a message
queue which does not exists. mq_open returns then -1 but errno is set
to 78 which is defined as this:
#define ENOSYS 78 /* Function not implemented */
The line in question:
res = mq_open ("/doesnotexist", O_RDWR);
"/doesnotexists" is the non-existing message queue the program tests
for. res will be set correctly to -1 but errno is set then to 78.
If I want to create the message queue, I will get the same error.
uname -a says:

Do I see or do something wrong or is this an error?
Erich
