FPATHCONF(3)        Linux Programmer's Manual        FPATHCONF(3)
+

+
+
NAME
+
       fpathconf, pathconf - get configuration values for files
+
+
SYNOPSIS
+
       #include <unistd.h>
+
+       long fpathconf(int filedes, int name);
+       long pathconf(char *path, int name);
+
+
DESCRIPTION
+
       fpathconf() gets a value for the configuration option name
+       for the open file descriptor filedes.
+
+       pathconf() gets a value for configuration option name  for
+       the file name path.
+
+       The  corresponding  macros  defined  in <unistd.h> minimum
+       values; if an application wants to take advantage of  val-
+       ues  which may change, a call to fpathconf() or pathconf()
+       can be made, which may yield more liberal results.
+
+       Setting name equal  to  one  of  the  following  constants
+       returns the following configuration options:
+
+       _PC_LINK_MAX
+              returns  the  maximum  number of links to the file.
+              If filedes or path refer to a directory,  then  the
+              value  applies  to the whole directory.  The corre-
+              sponding macro is _POSIX_LINK_MAX.
+
+       _PC_MAX_CANON
+              returns the maximum length  of  a  formatted  input
+              line,  where filedes or path must refer to a termi-
+              nal.  The corresponding macro is  _POSIX_MAX_CANON.
+
+       _PC_MAX_INPUT
+              returns  the maximum length of an input line, where
+              filedes or path must refer to a terminal.  The cor-
+              responding macro is _POSIX_MAX_INPUT.
+
+       _PC_NAME_MAX
+              returns  the  maximum  length  of a filename in the
+              directory path or filedes.  the process is  allowed
+              to create.  _POSIX_MAX_.
+
+       _PC_PATH_MAX
+              returns  the  maximum length of a relative pathname
+              when path or filedes is the current working  direc-
+              tory.   The corresponding macro is _POSIX_PATH_MAX.
+
+       _PC_PIPE_BUF
+              returns the size of the pipe buffer, where  filedes
+              must refer to a pipe or FIFO and path must refer to
+              a FIFO. The corresponding macro is _POSIX_PIPE_BUF.

+
+       _PC_CHOWN_RESTRICTED
+              returns  nonzero  if  the  chown(2) call may not be
+              used on this file.  If filedes or path refer  to  a
+              directory,  then  this applies to all files in that
+              directory.     The    corresponding    macro     is
+              _POSIX_CHOWN_RESTRICTED.
+
+       _PC_NO_TRUNC
+              returns  nonzero if accessing filenames longer than
+              _POSIX_NAME_MAX generates  an  error.   The  corre-
+              sponding macro is _POSIX_NO_TRUNC.
+
+       _PC_VDISABLE
+              returns nonzero if special character processing can
+              be disabled, where filedes or path must refer to  a
+              terminal.
+
+
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  errno is unchanged.  If there is an error,
+       -1 is returned, and errno is set to reflect the nature  of
+       the error.
+
+
CONFORMS TO
+
       POSIX.1  Files  with  name  lengths  longer than the value
+       returned for name equal to _PC_NAME_MAX may exist  in  the
+       given directory.
+
+       Some  returned  values  may be huge; they are not suitable
+       for allocating memory.
