I am having trouble handing "raw" data to a C function, using "cfunction", as
demonstrated in the function and output pasted below. Can anyone suggest what
I'm doing incorrectly? Thanks. Dan Kelley [Dalhousie University].
1. TEST FILE
library(inline)
code <- 'Rprintf("inside f(), b is 0X%x\\n", *b);'
f <- cfunction(sig=signature(b="raw"),
body=code,
convention=".C")
b <- as.raw(0x0f)
for (i in 1:5)
f(b)
2. SAMPLE OUTPUT FROM TEST FILE
inside f(), b is 0X70
inside f(), b is 0X80
inside f(), b is 0X70
inside f(), b is 0X60
inside f(), b is 0X50
