Linux 2.6 - man page for getwd (linux section 3posix)

GETWD(P)			    POSIX Programmer's Manual				 GETWD(P)

NAME
       getwd - get the current working directory pathname (LEGACY)

SYNOPSIS
       #include <unistd.h>

       char *getwd(char *path_name);

DESCRIPTION
       The getwd() function shall determine an absolute pathname of the current working directory
       of the calling process, and copy a string containing that pathname into the array  pointed
       to by the path_name argument.

       If  the	length	of  the  pathname  of  the  current  working  directory  is  greater than
       ({PATH_MAX}+1) including the null byte, getwd() shall fail and return a null pointer.

RETURN VALUE
       Upon successful completion, a pointer to the string containing the  absolute  pathname  of
       the  current  working  directory shall be returned. Otherwise, getwd() shall return a null
       pointer and the contents of the array pointed to by path_name are undefined.

ERRORS
       No errors are defined.

       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       For applications portability, the getcwd() function should be used to determine	the  cur-
       rent working directory instead of getwd().

RATIONALE
       Since  the  user  cannot  specify  the length of the buffer passed to getwd(), use of this
       function is discouraged. The length of a pathname described in {PATH_MAX} is file  system-
       dependent  and may vary from one mount point to another, or might even be unlimited. It is
       possible to overflow this buffer in such a way as to cause applications to fail, or possi-
       ble system security violations.

       It is recommended that the getcwd() function should be used to determine the current work-
       ing directory.

FUTURE DIRECTIONS
       This function may be withdrawn in a future version.
