NAME

6       genders_getnodename - get the current node name
7

SYNOPSIS

9       #include <genders.h>
10
11       int genders_getnodename(genders_t handle, char *node, int len);
12

DESCRIPTION

14       genders_getnodename()  retrieves the name of the node that the function
15       is being called from.  The node name returned is the shortened hostname
16       of the node and is stored in the buffer pointed to be node.  len should
17       indicate the length of the buffer.  The node returned by  genders_getn‐
18       odename() is the shortened hostname of the node.
19
20       To avoid passing in a buffer that is not large enough to store the node
21       name, genders_getmaxnodelen(3) should be used to determine the  minimum
22       buffer size that should be used.
23

RETURN VALUES

25       On success, 0 is returned.  On error, -1 is returned, and an error code
26       is returned in handle.  The  error  code  can  be  retrieved  via  gen‐
27       ders_errnum(3)  ,  and a description of the error code can be retrieved
28       via genders_strerror(3).  Error codes are defined in genders.h.
