NAME

       genders_getnodename - get the current node name

SYNOPSIS

       #include <genders.h>

       int genders_getnodename(genders_t handle, char *node, int len);

DESCRIPTION

       genders_getnodename() retrieves the name of the node that the function is being called from.  The node name returned is the shortened host-
       name of the node and is stored in the buffer pointed to be node.  len should indicate the length of the buffer.	The node returned by  gen-
       ders_getnodename() is the shortened hostname of the node.

       To avoid passing in a buffer that is not large enough to store the node name, genders_getmaxnodelen(3) should be used to determine the min-
       imum buffer size that should be used.

RETURN VALUES

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