SYNOPSIS

10       #include <nodeupdown.h>
11
12       int nodeupdown_errnum(nodeupdown_t handle);
13
14       char *nodeupdown_strerror(int errnum);
15
16       char *nodeupdown_errormsg(nodeupdown_t handle);
17
18       void nodeupdown_perror(nodeupdown_t handle, const char *msg);

DESCRIPTION

21       nodeupdown_errnum() returns the error code stored in handle.
22
23       nodeupdown_strerror() returns a pointer  to  a  string  describing  the
24       error code errnum.
25
26       Generally,  an  error code is retrieved by nodeupdown_errnum() and then
27       passed to nodeupdown_strerror().
28
29       nodeupdown_errormsg() returns a pointer  to  a  string  describing  the
30       error stored in handle.  It is logically equivalent to:
31
32       char *nodeupdown_strerror(nodeupdown_errnum(nodeupdown_t handle));
33
34       nodeupdown_perror()  is similar to perror(3).  It produces a message on
35       standard error output, describing the error stored in handle.   If  msg
36       is  not  NULL,  the  string pointed to by msg, a colon, and a blank are
37       printed before the error message.
