This turns on the silent REprintf in C when suppressMessages() is
turned on. This makes the REprintf act like messages in R,
they can be suppressed with suppressMessages()
Examples
# rxSupressMsg() is called with rxode2()
# Note the errors are output to the console
try(rxode2("d/dt(matt)=/3"), silent = TRUE)
#>
#>
# When using suppressMessages, the output is suppressed
suppressMessages(try(rxode2("d/dt(matt)=/3"), silent = TRUE))
# In rxode2, we use REprintf so that interrupted threads do not crash R
# if there is a user interrupt. This isn't captured by R's messages, but
# This interface allows the `suppressMessages()` to suppress the C printing
# as well
# If you want to suppress messages from rxode2 in other packages, you can use
# this function
