NAME
sana2perror - print SANA-II device error messages
SYNOPSIS
#include <devices/sana2.h>
sana2perror(banner, ios2request)
void sana2perror(const char *, struct IOSana2Req *)
FUNCTION
The sana2perror() function finds the error message corresponding to
the error in the given SANA-II IO request and writes it, followed by a
newline, to the stderr. If the argument string is non-NULL it is
preappended to the message string and separated from it by a colon and
space (`: '). If string is NULL only the error message string is
printed.
NOTES
The sana2perror() function requires the stdio functions to be linked.
