Implementation of GetCompressedFileSize[AW]

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello!

FIXME about GetCompressedFileSizeA was too annoying when running Cygwin
programs, so I implemented it.  The code uses st_blocks when possible to
account for sparse files and falls back to st_size if st_blocks is missing
in struct stat.  The code uses shift operations so that both systems with
32-bit and 64-bit off_t will do their best to provide accurate results.

ChangeLog:
	* configure.ac:
	Check for st_blocks in struct stat.
	* win32/newfns.c:
	Implement GetCompressedFileSize[AW].
