Error Codes pNA+ Error Codes
B.4 pNA+ Error Codes
When the pNA+ network manager generates an error, an error code is loaded into an
internal variable that can be read through the macro errno(). One errno variable
exists for each task. If the return value of a pNA+ system call indicates an error,
your application should examine the errno variable to determine the cause of the
error. See the description of errno() on page 3-27 for more information.
Table B-8 lists the error codes of the pNA+ network manager. Each listing includes
the error code’s hexadecimal number, its mnemonic and description, and the system
calls that can return it. The error code mnemonics are also defined in the file
.
