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 NAME
|
|
cpg_overview \- CPG library overview
|
|
.SH OVERVIEW
|
|
The CPG library is delivered with the corosync project. This library is used
|
|
to create distributed applications that operate properly during cluster
|
|
partitions, merges, and faults.
|
|
.PP
|
|
The library provides a mechanism to:
|
|
.PP
|
|
* handle abstraction for multiple instances of a CPG library in one application
|
|
.PP
|
|
* join one or more groups
|
|
.PP
|
|
* leave one or more groups
|
|
.PP
|
|
* Deliver messages to members of that group
|
|
.PP
|
|
* Deliver configuration changes
|
|
.PP
|
|
* Iterate members of groups
|
|
.PP
|
|
.SH SECURITY
|
|
If encryption is enabled in corosync.conf, the CPG library will encrypt and
|
|
authenticate message contents. Applications must run as the ais user to be
|
|
validated by corosync on IPC connection, otherwise they will be unable to
|
|
access the corosync services.
