-.TH FPATHCONF 3 2014-05-28 "GNU" "Linux Programmer's Manual"
-.SH NAME
-fpathconf, pathconf \- get configuration values for files
-.SH SYNOPSIS
-.nf
-.B #include <unistd.h>
-.sp
-.BI "long fpathconf(int " fd ", int " name );
-.br
-.BI "long pathconf(const char *" path ", int " name );
-.fi
-.SH DESCRIPTION
-.BR fpathconf ()
-gets a value for the configuration option
-.I name
-for the open file descriptor
-.IR fd .
-.PP
-.BR pathconf ()
-gets a value for configuration option
-.I name
-for the filename
-.IR path .
-.PP
-The corresponding macros defined in
-.I <unistd.h>
-are minimum values; if an application wants to take advantage of values
-which may change, a call to
-.BR fpathconf ()
-or
-.BR pathconf ()
-can be made, which may yield more liberal results.
-.PP
-Setting
-.I name
-equal to one of the following constants returns the following
-configuration options:
-.TP
-.B _PC_LINK_MAX
-returns the maximum number of links to the file.
-If
-.I fd
-or
-.I path
-refer to a directory, then the value applies to the whole directory.
-The corresponding macro is
-.BR _POSIX_LINK_MAX .
-.TP
-.B _PC_MAX_CANON
-returns the maximum length of a formatted input line, where
-.I fd
-or
-.I path
-must refer to a terminal.
-The corresponding macro is
-.BR _POSIX_MAX_CANON .
-.TP
-.B _PC_MAX_INPUT
-returns the maximum length of an input line, where
-.I fd
-or
-.I path
-must refer to a terminal.
-The corresponding macro is
-.BR _POSIX_MAX_INPUT .
-.TP
-.B _PC_NAME_MAX
-returns the maximum length of a filename in the directory
-.I path
-or
-.IR fd
-that the process is allowed to create.
-The corresponding macro is
-.BR _POSIX_NAME_MAX .
-.TP
-.B _PC_PATH_MAX
-returns the maximum length of a relative pathname when
-.I path
-or
-.I fd
-is the current working directory.
-The corresponding macro is
-.BR _POSIX_PATH_MAX .
-.TP
-.B _PC_PIPE_BUF
-returns the size of the pipe buffer, where
-.I fd
-must refer to a pipe or FIFO and
-.I path
-must refer to a FIFO.
-The corresponding macro is
-.BR _POSIX_PIPE_BUF .
-.TP
-.B _PC_CHOWN_RESTRICTED
-returns nonzero if the
-.BR chown (2)
-call may not be used on this file.
-If
-.I fd
-or
-.I path
-refer to a directory, then this applies to all files in that
-directory.
-The corresponding macro is
-.BR _POSIX_CHOWN_RESTRICTED .
-.TP
-.B _PC_NO_TRUNC
-returns nonzero if accessing filenames longer than
-.B _POSIX_NAME_MAX
-generates an error.
-The corresponding macro is
-.BR _POSIX_NO_TRUNC .
-.TP
-.B _PC_VDISABLE
-returns nonzero if special character processing can be disabled, where
-.I fd
-or
-.I path
-must refer to a terminal.
-.SH RETURN VALUE
-The limit is returned, if one exists.
-If the system does not have a
-limit for the requested resource, \-1 is returned, and
-.I errno
-is unchanged.
-If there is an error, \-1 is returned, and
-.I errno
-is set to reflect the nature of the error.
-.SH CONFORMING TO
-POSIX.1-2001.
-.SH NOTES
-Files with name lengths longer than the value returned for
-.I name
-equal to
-.B _PC_NAME_MAX
-may exist in the given directory.
-.PP
-Some returned values may be huge; they are not suitable for allocating
-memory.
