QNX documentation specifies the following return values for pthread_mutex_init()
EOK - Success.
EAGAIN - All kernel synchronization objects are in use.
EBUSY - The given mutex was previously initialized and hasn't been destroyed.
EFAULT - A fault occurred when the kernel tried to access mutex or attr.
EINVAL - The value specified by attr is invalid.
What would be correct handling for each of these code?
Also IEEE Std 1003.1-2008, specifies the following
[EAGAIN] - The system lacked the necessary resources (other than memory) to initialize another mutex.
[ENOMEM] - Insufficient memory exists to initialize the mutex.
[EPERM] - The caller does not have the privilege to perform the operation.
Why are ENOMEM and EPERM not specified in QNX?
EOK - Success.
