 Interface for user specific layout format of log4c\_logging\_event events.  file **layout\_type\_basic.h**\
 Implement a basic layout.  file **layout\_type\_basic\_r.h**\
 Implement a basic\_r layout.  file **layout\_type\_dated.h**\
 Implement a dated layout.  file **layout\_type\_dated\_local.h**\
 Implement a dated layout with local time.  file **layout\_type\_dated\_local\_r.h**\

 The internal representation of caller location information.  file **logging\_event.h**\
 the internal representation of logging events.  file **priority.h**\
 The priority class provides importance levels with which one can categorize log messages.  file **rc.h**\
 log4c resource configuration  file **rollingpolicy.h**\
 Log4c rolling policy interface. Defines the interface for managing and providing rolling policies.  file **rollingpolicy\_type\_sizewin.h**\
 Log4c rolling file size-win interface. Log4c ships with (and defaults to) the classic size-window rollover policy: this triggers rollover when files reach a maximum size. The first file in the list is always the current file; when a rollover event occurs files are shifted up by one position in the list--if the number of files in the list has already reached the max then the oldest file is rotated out of the window.  file **version.h**\
