commit 7e40e0169a75ebdf3f3861dab47abdfeb0ad9c58 Author: Corinna Vinschen <[email protected]> AuthorDate: Sun Jan 21 19:51:54 2024 +0100 Commit: Corinna Vinschen <[email protected]> CommitDate: Wed Jan 31 20:11:57 2024 +0100 Cygwin: implement dirent.d_reclen This change is in preparation of adding posix_getdents() from the upcoming POSIX Base Specification Issue 8. - Add d_reclen - Add GLibC compatible test macros for dirent members - Bump dirent version - Set d_reclen to the fixed size of the dirent struct We can do that because the size is a multiple of 8, so it fits snugly in the buffer filled by posix_getdents and keep the alignement.
