The _overview manpages are not actually commands and hence do not belong
into manpage section 8. Move corosync_overview to section 7
("Miscellaneous") and the other *_overview pages to section 3 as they
contain API documentation (cf. string(3) for precedence of
multi-function manpages).

.SH DESCRIPTION
|
|
.P
|
|
The
|
|
.B cmap_set
|
|
function is used to store key inside cmap. The
|
|
.I handle
|
|
argument is connection to CMAP database obtained by calling
|
|
.B cmap_initialize(3)
|
|
function.
|
|
.I 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._-/:]*.
|
|
.I value
|
|
is pointer to allocated data which will be stored inside CMAP. Length of value (number of bytes) is supplied
|
|
as
|
|
.I value_len
|
|
parameter. Last parameter is
|
|
.I type
|
|
which gives type of value. It may be one of:
|
|
.PP
|
|
\fBCMAP_VALUETYPE_INT8\fR - 8-bit signed integer
|
|
.PP
|
|
\fBCMAP_VALUETYPE_UINT8\fR - 8-bit unsigned integer
|
|
.PP
|
|
\fBCMAP_VALUETYPE_INT16\fR - 16-bit signed integer
|
|
.PP
|
|
\fBCMAP_VALUETYPE_UINT16\fR - 16-bit unsigned integer
|
|
.PP
|
|
\fBCMAP_VALUETYPE_INT32\fR - 32-bit signed integer
|
|
.PP
|
|
\fBCMAP_VALUETYPE_UINT32\fR - 32-bit unsigned integer
|
|
.PP
|
|
\fBCMAP_VALUETYPE_INT64\fR - 64-bit signed integer
|
|
.PP
|
|
\fBCMAP_VALUETYPE_UINT64\fR - 64-bit unsigned integer
|
|
.PP
|
|
\fBCMAP_VALUETYPE_FLOAT\fR - Float value
|
|
.PP
|
|
\fBCMAP_VALUETYPE_DOUBLE\fR - Double value
|
|
.PP
|
|
\fBCMAP_VALUETYPE_STRING\fR - C-style string
|
|
.PP
|
|
\fBCMAP_VALUETYPE_BINARY\fR - Binary data, byte with zero value has no special meaning
|
|
|
|
|
|
.SH 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.
