Expand description
Variable names for pathconf
Nix uses the same naming convention for these variables as the
getconf(1) utility.
That is, PathconfVar
variables have the same name as the abstract
variables shown in the pathconf(2)
man page. Usually, it’s the same as
the C variable name without the leading _PC_
.
POSIX 1003.1-2008 standardizes all of these variables, but some OSes choose not to implement variables that cannot change at runtime.

Variants (Non-exhaustive)
This enum is marked as non-exhaustive
FILESIZEBITS
Minimum number of bits needed to represent, as a signed integer value, the maximum size of a regular file allowed in the specified directory.
LINK_MAX
Maximum number of links to a single file.
MAX_CANON
Maximum number of bytes in a terminal canonical input line.
MAX_INPUT
Minimum number of bytes for which space is available in a terminal input queue; therefore, the maximum number of bytes a conforming application may require to be typed as input before reading them.
NAME_MAX
Maximum number of bytes in a filename (not including the terminating null of a filename string).
PATH_MAX
Maximum number of bytes the implementation will store as a pathname in a user-supplied buffer of unspecified size, including the terminating null character. Minimum number the implementation will accept as the maximum number of bytes in a pathname.
PIPE_BUF
Maximum number of bytes that is guaranteed to be atomic when writing to a pipe.
POSIX2_SYMLINKS
Symbolic links can be created.
POSIX_ALLOC_SIZE_MIN
Minimum number of bytes of storage actually allocated for any portion of a file.
POSIX_REC_INCR_XFER_SIZE
Recommended increment for file transfer sizes between the
POSIX_REC_MIN_XFER_SIZE
and POSIX_REC_MAX_XFER_SIZE
values.
POSIX_REC_MAX_XFER_SIZE
Maximum recommended file transfer size.
POSIX_REC_MIN_XFER_SIZE
Minimum recommended file transfer size.
POSIX_REC_XFER_ALIGN
Recommended file transfer buffer alignment.
SYMLINK_MAX
Maximum number of bytes in a symbolic link.
_POSIX_CHOWN_RESTRICTED
The use of chown
and fchown
is restricted to a process with
appropriate privileges, and to changing the group ID of a file only to
the effective group ID of the process or to one of its supplementary
group IDs.
_POSIX_NO_TRUNC
Pathname components longer than {NAME_MAX} generate an error.
_POSIX_VDISABLE
This symbol shall be defined to be the value of a character that shall disable terminal special character handling.
_POSIX_ASYNC_IO
Asynchronous input or output operations may be performed for the associated file.
_POSIX_PRIO_IO
Prioritized input or output operations may be performed for the associated file.
_POSIX_SYNC_IO
Synchronized input or output operations may be performed for the associated file.
