Dear All,
I'm wondering if the following statement about epicsTimer is correct or not.
#Start of the statement
Any handler of epicsTimer runs, when the timer expired, not in an interrupt
context but in a normal task's (thread's) context.
This goes for the case where the iocCore program is running on vxWorks or
RTEMS, or whatever OS supported in Base.
#End of the statement
What I'd like to know is, in other words, if a handler of epicsTimer is
allowed to take semaphores in the handler or not.
I guess the statement is TRUE because I have found an example of a handler
to call printf, in "IOC Application Developer's Guide (Chp.19, Section
10.4)".
Still, I feel I need to confirm it more...
Thanks a lot in advance.
