  GETWD(3C)                Standard C Library Functions                GETWD(3C)

  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.
         Otherwise, getwd() returns a null pointer and the contents of the array
         pointed to by path_name are undefined.
