Error Reference

All YumaPro programs use the same set of error numbers and error messages.
Error numbers are 3 digit unsigned integers in the range 1 to 999. The number 0 is reserved for the NO_ERR constant, which is the same as the <ok/> status returned by the server.
The file ncx/status_enum.h contains the status_t enumeration typedef.
Error Number Types
range	description
0	no error
1	EOF
2 - 99	internal program errors
100 to 199	system errors
200 to 999	user errors
1000 to 1999	warnings
2000 to 2999	informational messages
Error Messages

The current list of error numbers and default error messages can be obtained with the yangdump-pro program --show-errors parameter. The enumerations for the The default error message can be replaced for some error conditions with the YANG "error-message" statement.
The following list shows the default error messages for all error numbers currently in use.
