10.1088 statvfs

POSIX specification:
https://pubs.opengroup.org/onlinepubs/9699919799/functions/statvfs.html

Gnulib module: —

Portability problems fixed by Gnulib:

• On platforms where f_blocks in ‘struct statvfs’ is a 32-bit value, this function may not work correctly on files systems larger than 4 TiB. See Large File Support. This affects glibc/Hurd, HP-UX 11, Solaris.

Portability problems not fixed by Gnulib:

• This function is missing on some platforms: OpenBSD 3.8, mingw, MSVC 14, Android 4.3.
• This function can hang if it stats all preceding entries in /proc/mounts, and any of those file systems are hard-mounted and not available. This affects Linux < 2.6.36.

Gnulib provides a module fsusage that provides similar information as statvfs.
