genders_getnodename - get the current node name

genders_getnodename()  retrieves  the  name of the node that the function is being called from.  The node
       name returned is the shortened hostname 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 genders_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 minimum buffer size that should be used.

GENDERS_ERR_NULLHANDLE
              The handle parameter is NULL.  The genders handle must be created with genders_handle_create(3).

       GENDERS_ERR_NOTLOADEDgenders_load_data(3) has not been called to load genders data.

       GENDERS_ERR_OVERFLOW
              The buffer pointed to by node is not large enough to store the node name.

       GENDERS_ERR_PARAMETERS
              An incorrect parameter has been passed in.

       GENDERS_ERR_MAGIChandle has an incorrect magic number.  handle does not point to a genders  handle  or  handle  has
              been destroyed by genders_handle_destroy(3).

       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 genders_errnum(3) , and a description of the error code can be retrieved via
       genders_strerror(3).  Error codes are defined in genders.h.
