msg − print diagnostic
#include <libowfat/errmsg.h>
void msg(const char *message, ...);
If errmsg_iam was called to set the program name, msg will first print that program name and a colon.
msg will print all its arguments to stdout (fd #1).
It does not synchronize with any other output method.
If you have unflushed data in buffer_1, it will stay there.
errmsg(7), buffer_flush(3)
