CMAP_SET(3)	  Corosync Cluster Engine Programmer's Manual	   CMAP_SET(3)

       cmap_set - Store value in CMAP

       #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);

       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 spe‐
       cial meaning

       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.

       cmap_get(3), cmap_initialize(3), cmap_overview(8)

       CS_ERR_TRY_AGAIN Resource temporarily unavailable

       CS_ERR_INVALID_PARAM Invalid argument

       CS_ERR_ACCESS Permission denied

       CS_ERR_LIBRARY The connection failed

       CS_ERR_INTERRUPT System call inturrupted by a signal

       CS_ERR_NOT_SUPPORTED The requested protocol/functuality not supported

       CS_ERR_MESSAGE_ERROR Incorrect auth message received

       CS_ERR_NO_MEMORY Not enough memory to completed the requested task
