       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_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_initialize(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 integer

       CMAP_VALUETYPE_UINT8 - 8-bit unsigned integer

       CMAP_VALUETYPE_INT16 - 16-bit signed integer

       CMAP_VALUETYPE_UINT16 - 16-bit unsigned integer

       CMAP_VALUETYPE_INT32 - 32-bit signed integer

       CMAP_VALUETYPE_UINT32 - 32-bit unsigned integer

       CMAP_VALUETYPE_INT64 - 64-bit signed integer

       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  setting  such key will result in
       CS_ERR_ACCESS error.
