genders_getnodename - get the current node name
int genders_getnodename(genders_t handle, char *node, int len);
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.
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
