Include "backupfile.h" first. Include errno.h, stdbool.h, limits.h, unistd.h, xalloc.h. (CLOSEDIR, INT_STRLEN_BOUND): Remove. (pathconf) [! (HAVE_PATHCONF && defined _PC_NAME_MAX)]: New macro. (_POSIX_NAME_MAX) [!defined _POSIX_NAME_MAX]: New macro. (NAME_MAX_MAXIMUM): New macro. Unlike the old addext.c, we also look at _XOPEN_NAME_MAX, for better performance on modern hosts that support only file names of length 255 or more. (ISDIGIT): unsigned -> unsigned int (max_backup_version, version_number): Remove. (check_extension): New function. Similar to the old addext, but static, assumes that the extension has already been added, and a bit more careful on DOS hosts. (numbered_backup): New function. It does what max_backup_version and version_number used to do, but it doesn't use integer arithmetic to calculate extensions so it doesn't overflow. (find_backup_file_name): Rewrite to use these new functions. This has a new optimization: we needn't call pathconf if the new numbered backup name has the same length as the old. Also, use xmalloc rather than malloc, so that the caller needn't worry about memory exhaustion. (FILE_SYSTEM_PREFIX_LEN): Renamed from 2004-06-30T22:38:03Z Jim Meyering jim@meyering.net 2004-06-30T22:38:03Z urn:sha1:49d4a73415159c186681df46e684d3190371ea8f FILESYSTEM_PREFIX_LEN. All uses changed. Include <string.h>, <stdlib.h> unconditionally. 2003-09-10T08:26:42Z Jim Meyering jim@meyering.net 2003-09-10T08:26:42Z urn:sha1:0d84cc66ee79ccd92f4c30548ceaa632dd7d3144 Don't declare getenv or malloc.
