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 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_getn-
odename() 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 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.
ERRORS
GENDERS_ERR_NULLHANDLE
The handle parameter is NULL. The genders handle must be cre-
ated with genders_handle_create(3).
GENDERS_ERR_NOTLOADED
genders_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_MAGIC
handle has an incorrect magic number. handle does not point to
a genders handle or handle has been destroyed by genders_han-
dle_destroy(3).
