NAME
       getwd - get current working directory pathname

SYNOPSIS
       #include <unistd.h>

       char *getwd(char *path_name);

DESCRIPTION
       The getwd() function determines an absolute pathname of the current working directory of the calling process, and copies 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()	fails  and
       returns a null pointer.

RETURN VALUES
       Upon  successful completion, a pointer to the string containing the absolute pathname of the current working directory is returned.  Other-
       wise, getwd() returns a null pointer and the contents of the array pointed to by path_name are undefined.

ERRORS
       No errors are defined.

USAGE
       For portability to implementations conforming to versions of the X/Open Portability Guide prior to SUS, getcwd(3C) is preferred	over  this
       function.
