mkstemp() generates a temporary file name and open the corresponding file with a 32bits system call (no 64bits version for this function in AIX libc). So I/O operations on the returned 32bits file descriptor will fail after the 2GB limit. By skipping mkstemp() function use, mktemp() + 64bits open() syscall (if _LARGE_FILES defined) will be used, that will allow >2GB files. Linux libc have a 64bits version of mkstemp() : Linux(2.4.19)# nm /lib/libc.so.6 |grep mkstemp 000c65a0 T mkstemp 000c65e0 T mkstemp64 Solaris too: SunOS(2.8)# nm /lib/libc.so |grep mkstemp|grep FUNC [3538] | 274264| 224|FUNC |GLOB |0 |9 |_mkstemp [3294] | 213800| 224|FUNC |GLOB |0 |9 |_mkstemp64 [4662] | 274264| 224|FUNC |WEAK |0 |9 |mkstemp [3668] | 213800| 224|FUNC |WEAK |0 |9 |mkstemp64 and AIX gives : AIX(5.1 ML3)# nm /lib/libc.a|grep mkstemp mkstemp D 254912 12 .mkstemp T 1110564 ../../../../../../../src/bos/usr/ccs/lib/libc/mkstemp.c f - Poor AIX users/programmers ! -- To unsubscribe or change options: http://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.tuxedo.org/~esr/faqs/smart-questions.html
