CONFDB_KEY_ITER(3) Corosync Cluster Engine Programmer's Manual CONFDB_KEY_ITER(3) NAME
confdb_key_iter - Iterate through key/value pairs in the Configuration Database SYNOPSIS
#include <corosync/confdb.h> confdb_error_t confdb_key_iter_start(confdb_handle_t handle, unsigned int parent_object_handle ); confdb_error_t confdb_key_iter(confdb_handle_t handle, unsigned int parent_object_handle, void *key_name, int *key_name_len, void *value, int *value_len ); DESCRIPTION
The confdb_key_iter function repeatedly returns all key/value pairs that are subobjects of the specified parent. You must call confdb_key_iter_start first. This establishes a context for the parent object so that it knows where you are in the list. Then the next call to confdb_key_iter will return the first key/value in the list. Subsequent calls will return any remaining keys. The function returns CONFDB_ERR_ACCESS when the all of the matching keys have been seen. The library holds a seperate context for each parent object, so you can call confdb_key_iter() on several parent objects at the same time and they will not interfere. Nor will they interfere with confdb_object_find or confdb_object_iter calls on the same parent object. RETURN VALUE
This call returns the CONFDB_OK value if successful, otherwise an error is returned. ERRORS
The errors are undocumented. SEE ALSO

cmap_set - Store value in CMAP SYNOPSIS
#include <corosync/cmap.h> cs_error_t cmap_set (cmap_handle_t handle, const char *key_name, const void *value, size_t value_len, cmap_value_types_t type); Also shortcuts for different types are defined cs_error_t cmap_set_int8(cmap_handle_t handle, const char *key_name, int8_t value); cs_error_t cmap_set_uint8(cmap_handle_t handle, const char *key_name, uint8_t value); cs_error_t cmap_set_int16(cmap_handle_t handle, const char *key_name, int16_t value); cs_error_t cmap_set_uint16(cmap_handle_t handle, const char *key_name, uint16_t value); cs_error_t cmap_set_int32(cmap_handle_t handle, const char *key_name, int32_t value); cs_error_t cmap_set_uint32(cmap_handle_t handle, const char *key_name, uint32_t value); cs_error_t cmap_set_int64(cmap_handle_t handle, const char *key_name, int64_t value); cs_error_t cmap_set_uint64(cmap_handle_t handle, const char *key_name, uint64_t value); cs_error_t cmap_set_float(cmap_handle_t handle, const char *key_name, float value); cs_error_t cmap_set_double(cmap_handle_t handle, const char *key_name, double value); cs_error_t cmap_set_string(cmap_handle_t handle, const char *key_name, const char *value); DESCRIPTION
The cmap_set function is used to store key inside cmap. The handle argument is connection to CMAP database obtained by calling cmap_ini- tialize(3) function. key_name is name of key to set value. Key name is limited by minimal (CMAP_KEYNAME_MINLEN, currently 3) and maximal (CMAP_KEYNAME_MAXLEN, currently 255) length. Also key can contain only limited set of characters expressed by regexp [a-zA-Z0-9._-/:]*. value is pointer to allocated data which will be stored inside CMAP. Length of value (number of bytes) is supplied as value_len parameter. Last parameter is type which gives type of value. It may be one of: CMAP_VALUETYPE_INT8 - 8-bit signed interger CMAP_VALUETYPE_UINT8 - 8-bit unsigned integer CMAP_VALUETYPE_INT16 - 16-bit signed interger CMAP_VALUETYPE_UINT16 - 16-bit unsigned integer CMAP_VALUETYPE_INT32 - 32-bit signed interger CMAP_VALUETYPE_UINT32 - 32-bit unsigned integer CMAP_VALUETYPE_INT64 - 64-bit signed interger CMAP_VALUETYPE_UINT64 - 64-bit unsigned integer CMAP_VALUETYPE_FLOAT - Float value CMAP_VALUETYPE_DOUBLE - Double value CMAP_VALUETYPE_STRING - C-style string CMAP_VALUETYPE_BINARY - Binary data, byte with zero value has no special meaning RETURN VALUE
This call returns the CS_OK value if successful. If value or key_name are unspecified, CS_ERR_INVALID_PARAM is returned. Too short or too long key_name returns CS_ERR_NAME_TOO_LONG error code. Some of keys may be tagged read-only directly in corosync and seting such key will result in CS_ERR_ACCESS error. SEE ALSO
