Check if file is a named pipe (fifo) in C ++

Question

I have a reader from the file "foo" using C ++ using:

pFile = fopen ("foo" , "r");

I want it to stop the rest of the function if the file is a named pipe. Is there a way to check if a file is a named pipe before opening it?

I found the same question using python: Check if file is a named pipe (fifo) in python? Can I do something like this in C ++?

Answer 1

From man 2 stat:

int fstat(int filedes, struct stat *buf);

... The following POSIX macros are defined for checking the file type using the st_mode field:

         S_ISFIFO(m) FIFO (named pipe)?

struct stat st;... !fstat(fileno(pFile, &st) && S_ISFIFO(st.st_mode) struct stat st;... !fstat(fileno(pFile, &st) && S_ISFIFO(st.st_mode) .
