Typedef Documentation

◆ GLogField

typedef struct _GLogField GLogField

GLogField: @key: field name (UTF-8 string) @value: field value (arbitrary bytes) @length: length of @value, in bytes, or -1 if it is nul-terminated

Structure representing a single field in a structured log entry. See g_log_structured() for details.

Log fields may contain arbitrary values, including binary with embedded nul bytes. If the field contains a string, the string must be UTF-8 encoded and have a trailing nul byte. Otherwise, @length must be set to a non-negative value.

Since: 2.50

Definition at line 158 of file gmessages.h.

◆ GLogFunc

typedef void(* GLogFunc) (const gchar *log_domain, GLogLevelFlags log_level, const gchar *message, gpointer user_data)

Definition at line 75 of file gmessages.h.

◆ GLogWriterFunc

typedef GLogWriterOutput(* GLogWriterFunc) (GLogLevelFlags log_level, const GLogField *fields, gsize n_fields, gpointer user_data)

GLogWriterFunc: @log_level: log level of the message @fields: (array length=n_fields): fields forming the message @n_fields: number of @fields @user_data: user data passed to g_log_set_writer_func()

Writer function for log entries. A log entry is a collection of one or more #GLogFields, using the standard field names from journal specification. See g_log_structured() for more information.

Writer functions must ignore fields which they do not recognise, unless they can write arbitrary binary output, as field values may be arbitrary binary.

@log_level is guaranteed to be included in @fields as the PRIORITY field, but is provided separately for convenience of deciding whether or where to output the log entry.

Writer functions should return G_LOG_WRITER_HANDLED if they handled the log message successfully or if they deliberately ignored it. If there was an error handling the message (for example, if the writer function is meant to send messages to a remote logging server and there is a network error), it should return G_LOG_WRITER_UNHANDLED. This allows writer functions to be chained and fall back to simpler handlers in case of failure.

Returns: G_LOG_WRITER_HANDLED if the log entry was handled successfully; G_LOG_WRITER_UNHANDLED otherwise

Since: 2.50

Definition at line 197 of file gmessages.h.

◆ GPrintFunc

typedef void(* GPrintFunc) (const gchar *string)

GPrintFunc: @string: the message to output

Specifies the type of the print handler functions. These are called with the complete formatted string to output.

◆ GLogWriterOutput

enum GLogWriterOutput

GLogWriterOutput: @G_LOG_WRITER_HANDLED: Log writer has handled the log entry. @G_LOG_WRITER_UNHANDLED: Log writer could not handle the log entry.

Return values from #GLogWriterFuncs to indicate whether the given log entry was successfully handled by the writer, or whether there was an error in handling it (and hence a fallback writer should be used).

If a GLogWriterFunc ignores a log entry, it should return G_LOG_WRITER_HANDLED.

Since: 2.50
