Error recovery
All of the SMUX routines return NOTOK on failure.
The function
char * smux_error(smux_errno)
extern int smux_errno;
returns an appropriate string based on the error number passed to it.
The parameter value is set by functions in the SMUX/SNMP
library and the value could be any of:
parameterMissing,
invalidOperation,
inProgress,
systemError,
congestion, or
youLoseBig.
The variable
extern char smux_info[BUFSIZ];
contains a printable explanation of what caused the failure.
All errors are FATAL except inProgress;
if the error code is inProgress, the peer program
continues retrying the file descriptor for writability,
and then calls smux_simple_open again.
Otherwise, the program takes the appropriate action
based on the error code returned.
