NAME

       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.

Detailed Description

       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.

       If the max file size is set to zero, this means 'no-limit'.

       The default parameters for the size-win policy are 5 files of maximum size of 20kilobytes each. These
       parameters may be changed using the appropriate setter functions.

Function Documentation

   LOG4C_API rollingpolicy_sizewin_udata_t* sizewin_make_udata (void) Get a new size-win rolling policy
       Returns:
           a new size-win rolling policy, otherwise NULL.

   LOG4C_API int sizewin_udata_set_appender (rollingpolicy_sizewin_udata_t *swup, log4c_appender_t *app) Set the
       rolling file appender in this rolling policy configuration.
       Parameters:
           swup the size-win configuration object.
           app the rolling file appender to set.

       Returns:
           zero if successful, non-zero otherwise.

   LOG4C_API int sizewin_udata_set_file_maxsize (rollingpolicy_sizewin_udata_t *swup, longmax_size) Set the
       maximum file size in this rolling policy configuration.
       Parameters:
           swup the size-win configuration object.
           max_size the approximate maximum size any logging file will attain. If you set zero then it means
           'no-limit' and so only one file of unlimited size will be used for logging.

       Returns:
           zero if successful, non-zero otherwise.

   LOG4C_API int sizewin_udata_set_max_num_files (rollingpolicy_sizewin_udata_t *swup, longmax_num) Set the
       maximum number of filesin this rolling policy configuration.
       Parameters:
           swup the size-win configuration object.
           max_num the maximum number of files in the list.

       Returns:
           zero if successful, non-zero otherwise.
