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