NAME
genders_getnodename - get the current node nameSYNOPSIS
#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 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.
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 genders_errnum(3) , and a description of the error code can be retrieved via genders_strerror(3). Error codes are defined in genders.h.ERRORS

- GENDERS_ERR_OVERFLOW
