From 42893aa38fd6041d349ea0427c4d5ccbacd9a2be Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Thu, 24 Oct 2019 14:34:46 +0200 Subject: y2038: linux: Provide __futimens64 implementation This patch provides new __futimens64 explicit 64 bit function for setting access and modification time of file (by using its file descriptor). Moreover, a 32 bit version - __futimens has been refactored to internally use __futimens64. The __futimens is now supposed to be used on systems still supporting 32 bit time (__TIMESIZE != 64) - hence the necessary conversions to 64 bit struct __timespec64. When pointer to struct __timespec64 is NULL - the file access and modification time is set to the current one (by the kernel) and no conversions from struct timespec to __timespec64 are performed. The __futimens64 reuses __utimensat64_helper defined for __utimensat64. The test procedure for __futimens64 is the same as for __utimensat64 conversion patch. --- include/time.h | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'include/time.h') diff --git a/include/time.h b/include/time.h index 7debf9f9cc..8ac58e891b 100644 --- a/include/time.h +++ b/include/time.h @@ -158,6 +158,13 @@ extern int __utimensat64_helper (int fd, const char *file, const struct __timespec64 tsp[2], int flags); libc_hidden_proto (__utimensat64_helper); +#if __TIMESIZE == 64 +# define __futimens64 __futimens +#else +extern int __futimens64 (int fd, const struct __timespec64 tsp[2]); +libc_hidden_proto (__futimens64); +#endif + /* Compute the `struct tm' representation of T, offset OFFSET seconds east of UTC, and store year, yday, mon, mday, wday, hour, min, sec into *TP. -- cgit v1.2.3
