fchdir

chdir(2)							System Calls Manual							  chdir(2)

NAME

       chdir, fchdir - Changes the current directory

SYNOPSIS

       #include <unistd.h>

       int chdir (	const char *path );

       int fchdir (	 int filedes );

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       chdir():  XSH5.0

       fchdir():  XSH5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Points to the pathname of the directory.  Specifies the file descriptor of the directory.

DESCRIPTION

       The chdir() function changes the current directory to the directory indicated by the path parameter.

       The fchdir() function changes the current directory to the directory indicated by the filedes parameter.  If the path parameter refers to a
       symbolic link, thechdir() function sets the current directory to the directory pointed to by the symbolic link.

       The current directory, also called the current working directory, is the starting point of searches for pathnames that do not begin with  a
       / (slash).   In order for a directory to become the current directory, the calling process must have search access to the directory.

NOTES

       The  current  working directory is shared between all threads within the same process.  Therefore, one thread using the chdir() or fchdir()
       functions will affect every other thread in that process.

RETURN VALUES

       Upon successful completion, the chdir() function returns a value of 0 (zero).  Otherwise, a value of -1 is returned and	errno  is  set	to
       indicate the error.

ERRORS

       If  the	chdir() function fails, the current directory remains unchanged and errno may be set to one of the following values: Search access
       is denied for any component of the pathname.  The path parameter points outside the  process's  allocated  address  space.   An	I/O  error
       occurred  while	reading  from  or  writing to the file system.	Too many symbolic links were encountered in translating the pathname.  The
       length of the path argument exceeds PATH_MAX or a pathname component is longer than NAME_MAX.

	      Pathname resolution of a symbolic link produced an intermediate result whose length exceeds PATH_MAX.  The named directory does  not
	      exist, or is an empty string.  A component of the path prefix is not a directory.

       If  the	fchdir()  function fails, the current directory remains unchanged and errno may be set to one of the following values: The filedes
       parameter is not a valid open file descriptor.  The file descriptor does not reference a directory.
