carp − print warning diagnostic
#include <libowfat/errmsg.h>
void carp(const char *message, ...);
If errmsg_iam was called to set the program name, carp will first print that program name and a colon.
carp will print all its arguments to stderr (fd #2).
It does not synchronize with any other output method.
If you have unflushed data in buffer_2, it will stay there.
errmsg(7), buffer_flush(3)
