The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
quorum_context_set – Sets the context variable for a QUORUM instance Synopsis #include <corosync/quorum.h> int quorum_context_set(quorum_handle_t handle, void *context); Description The quorum_context_set function is used to set the context variable for a quorum instance.
