Are there large file non-standard C functions on your box - like fopen64?
I would expect that to be true, and you need to use them to be able to write to large files, ie 64 bit file pointers required.
All of the system level calls obviously support this or you could not get a positive file size larger then what the 32 bit ssize_t datatype supports.

log4c_rollingpolicy_sizewin_udata_t
rollingpolicy_type_sizewin.h(3) log4c rollingpolicy_type_sizewin.h(3)
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.
SYNOPSIS
#include <log4c/defs.h>
#include <log4c/rollingpolicy.h>
Typedefs
typedef struct __sizewin_udata rollingpolicy_sizewin_udata_t
Functions
LOG4C_API rollingpolicy_sizewin_udata_t * sizewin_make_udata (void)
LOG4C_API int sizewin_udata_set_file_maxsize (rollingpolicy_sizewin_udata_t *swup, long max_size)
LOG4C_API int sizewin_udata_set_max_num_files (rollingpolicy_sizewin_udata_t *swup, long max_num)
LOG4C_API int sizewin_udata_set_appender (rollingpolicy_sizewin_udata_t *swup, log4c_appender_t *app)
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.

typedef struct __sizewin_udata rollingpolicy_sizewin_udata_t log4c size-win rolling policy type
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.
