Detailed Description
Implement this interface for your own strategies for printing log statements.
Todo
- the appender interface needs a better configuration system depending on the layout type. The udata field is a just a trick.
Define Documentation
#define log4c_appender_type_define(a_type)
Helper macro to define static appender types.
Parameters:
- a_type the log4c_appender_type_t object to define
Warning:
- needs GCC support: otherwise this macro does nothing
Deprecated
- This macro, and the static initialialization of appenders in general, is deprecated. Use rather the log4c_appender_type_set() function to initialize your appenders before calling log4c_init()
Typedef Documentation
typedef struct __log4c_appender log4c_appender_t
log4c appender class
Function Documentation
LOG4C_API int log4c_appender_append (log4c_appender_t * this, log4c_logging_event_t * a_event)
log in appender specific way.
Parameters:
- a_appender the log4c_appender object
a_event the log4c_logging_event_t object to log.
Bug
- is this the right place to open an appender ?
References log4c_logging_event_t::evt_msg, and log4c_logging_event_t::evt_rendered_msg.
LOG4C_API int log4c_appender_close (log4c_appender_t * a_appender)
closes the appender
Parameters:
- a_appender the log4c_appender_t object
Returns:
- zero if successful, -1 otherwise
LOG4C_API void log4c_appender_delete (log4c_appender_t * a_appender)
Destructor for log4c_appender_t.
LOG4C_API log4c_appender_t* log4c_appender_get (const char * a_name)
Get a pointer to an existing appender.
Parameters:
- a_name the name of the appender to return.
Returns:
- a pointer to an existing appender, or NULL if no appender with the specfied name exists.
LOG4C_API const log4c_layout_t* log4c_appender_get_layout (const log4c_appender_t * a_appender)

LOG4C_API const log4c_appender_type_t* log4c_appender_get_type (const log4c_appender_t * a_appender)
Parameters:
- a_appender the log4c_appender_t object
Returns:
- the appender operations
LOG4C_API void* log4c_appender_get_udata (const log4c_appender_t * a_appender)
Parameters:
- a_appender the log4c_appender_t object
Returns:
- the appender user data
LOG4C_API log4c_appender_t* log4c_appender_new (const char * a_name)
Constructor for log4c_appender_t.
LOG4C_API int log4c_appender_open (log4c_appender_t * a_appender)
opens the appender.
Parameters:
- a_appender the log4c_appender_t object
LOG4C_API void log4c_appender_print (const log4c_appender_t * a_appender, FILE * a_stream)
prints the appender on a stream
Parameters:
- a_appender the log4c_appender_t object
a_stream the stream
LOG4C_API const log4c_layout_t* log4c_appender_set_layout (log4c_appender_t * a_appender, const log4c_layout_t * a_layout)
sets the appender layout
Parameters:
- a_appender the log4c_appender_t object
a_layout the new appender layout
Returns:
- the previous appender layout
LOG4C_API const log4c_appender_type_t* log4c_appender_set_type (log4c_appender_t * a_appender, const log4c_appender_type_t * a_type)
sets the appender type
Parameters:
- a_appender the log4c_appender_t object
a_type the new appender type
Returns:
- the previous appender type
LOG4C_API void* log4c_appender_set_udata (log4c_appender_t * a_appender, void * a_udata)
sets the appender user data
Parameters:
- a_appender the log4c_appender_t object
a_udata the new appender user data
Returns:
- the previous appender user data
LOG4C_API const log4c_appender_type_t* log4c_appender_type_get (const char * a_name)
Get a pointer to an existing appender type.
Parameters:
- a_name the name of the appender type to return.
Returns:
- a pointer to an existing appender type, or NULL if no appender type with the specified name exists.
LOG4C_API const log4c_appender_type_t* log4c_appender_type_set (const log4c_appender_type_t * a_type)
Use this function to register an appender type with log4c. Once this is done you may refer to this type by name both programmatically and in the log4c configuration file.
Parameters:
- a_type a pointer to the new appender type to set.
Returns:
- a pointer to the previous appender type of same name.
Example code fragment:
const log4c_appender_type_t log4c_appender_type_s13_file = { 's13_file', s13_file_open, s13_file_append, s13_file_close, }; log4c_appender_type_set(&log4c_appender_type_s13_file);
References log4c_appender_type::name.
LOG4C_API void log4c_appender_types_print (FILE * fp)
prints all the current registered appender types on a stream
Parameters:
- fp the stream
