5.3.2.6 Posix profile
The profile characteristics are:
• Process creation
SDL Task priority depend of the OS or RTOS you are using.
• On Solaris the priority parameter should be between 0 and 59
• On Linux the priority parameter should be between 0 and 99. Note the priority will only work if user has superuser privilege.
Default SDL-RT priority is 20 for Solaris and 50 for Linux and for both platforms
higher values correspond to higher priorities.
• Timers
The time value is set in milliseconds.
• Semaphores
• FIFO and PRIO parameters are ignored. Semaphore waiting queues are
always FIFO based.
• When using mutex semaphores DELETE_SAFE and INVERSION_SAFE have
no effect.
• When taking a semaphore the only options available are NO_WAIT and FOREVER and any other number of milliseconds will be understood as FOREVER.
