NAME
nodeupdown_get_up_nodes_string, nodeupdown_get_down_nodes_string, - get up or down nodesSYNOPSIS
#include <nodeupdown.h>int nodeupdown_get_up_nodes_string(nodeupdown_t handle, char *buf, int buflen);
int nodeupdown_get_down_nodes_string(nodeupdown_t handle, char *buf, int buflen);
DESCRIPTION
nodeupdown_get_up_nodes_string() retrieves a ranged string of nodes that are up and places it in the buffer pointed to by buf. buflen should indicate the length of the buffer. nodeupdown_get_down_nodes_string() is identical to nodeupdown_get_up_nodes_string(), except that it retrieves a ranged string of down nodes.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 nodeupdown_errnum(3) , and a description of the error code can be retrieved via nodeupdown_strerror(3). Error codes are defined in nodeupdown.h.ERRORS
- NODEUPDOWN_ERR_NULLHANDLE
- The handle parameter is NULL. The nodeupdown handle must be created with nodeupdown_handle_create(3).
- NODEUPDOWN_ERR_NOTLOADED
- nodeupdown_load_data(3) has not been called and no data has been retrieved.
- NODEUPDOWN_ERR_PARAMETERS
- An incorrect parameter has been passed in.
- NODEUPDOWN_ERR_OVERFLOW
- The buffer pointed to by buf is not large enough to store the ranged string of nodes.
- NODEUPDOWN_ERR_OUTMEM
- malloc(3) has failed internally.
- NODEUPDOWN_ERR_CLUSTERLIST_MODULE
- Internal error with the clusterlist module
- NODEUPDOWN_ERR_HOSTLIST
- Hostlist API has failed internally.
- NODEUPDOWN_ERR_MAGIC
- handle has an incorrect magic number. handle does not point to a nodeupdown handle or handle has been destroyed by nodeupdown_handle_destroy(3).
