NAME cmap_fd_get – Dispatches callbacks from the CMAP service SYNOPSIS #include <corosync/cmap.h> cs_error_t cmap_fd_get (cmap_handle_t handle, int *fd); DESCRIPTION The cmap_fd_get function is used to retrieve the file descriptor that may be used with the poll system call to determine when cmap_dispatch(3) won’t block. The handle argument may not be used directly with poll because…
NAME cmap_dispatch – Dispatches callbacks from the CMAP service SYNOPSIS #include <corosync/cmap.h> cs_error_t cmap_dispatch (cmap_handle_t handle, cs_dispatch_flags_t dispatch_types); DESCRIPTION The cmap_dispatch function is used to dispatch configuration changes. Each application may have several connections to the CMAP API. Each application uses the handle argument to uniquely identify the connection. The dispatch_types argument is used to…
NAME cmap_delete – Delete key/value pair from the CMAP service SYNOPSIS #include <corosync/cmap.h> cs_error_t cmap_delete(cmap_handle_t handle, const char *key_name); DESCRIPTION The cmap_delete function is used to delete key from cmap. Key must be previously created by cmap_set(3) function. The handle argument is connection to CMAP database obtained by calling cmap_initialize(3) function. key_name is name of…
NAME cmap_inc – Decrease already stored value in CMAP SYNOPSIS #include <corosync/cmap.h> cs_error_t cmap_dec (cmap_handle_t handle, const char *key_name); DESCRIPTION The cmap_dec function is used to decrease integer value of already stored 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 increase…
NAME cmap_context_set – Sets the context variable for a CMAP instance SYNOPSIS #include <corosync/cmap.h> cs_error_t cmap_context_set (cmap_handle_t handle, const void *context); DESCRIPTION The cmap_context_set function is used to store the context variable for cmap instance. It has no meaning insire libcmap itself and will not be touched by the library. It can be retrieved using…
NAME cmap_context_get – Gets the context variable for a CMAP instance SYNOPSIS #include <corosync/cmap.h> cs_error_t cmap_context_get (cmap_handle_t handle, const void **context); DESCRIPTION The cmap_context_get function is used to retrieve the context variable previously stored using cmap_context_set(3). RETURN VALUE This call returns the CS_OK value if successful, otherwise an error is returned. SEE ALSO cmap_context_set(3), cmap_overview(8)…

NAME closelog, openlog, syslog, vsyslog – send messages to the system logger SYNOPSIS #include <syslog.h> void openlog(const char *ident, int option, int facility); void syslog(int priority, const char *format, …); void closelog(void); void vsyslog(int priority, const char *format, va_list ap); Feature Test Macro Requirements for glibc (see feature_test_macros(7)): vsyslog(): Since glibc 2.19: _DEFAULT_SOURCE Glibc 2.19…
NAME closedir – close a directory SYNOPSIS #include <dirent.h> #include <sys/types.h> int closedir(DIR *dirp); DESCRIPTION The closedir() function closes the directory stream associated with dirp. A successful call to closedir() also closes the underlying file descriptor associated with dirp. The directory stream descriptor dirp is not available after this call. RETURN VALUE The closedir() function…
