GETWD(3)                   Library Functions Manual                   GETWD(3)

NAME
       getwd, getcwd - get current directory

SYNOPSIS
       char *getwd(buf)
       char *buf;

       char *getcwd(buf, size)
       char *buf;

DESCRIPTION
       Both  routines  fill buf with a null-terminated string representing the
       current directory and return buf.  A null pointer is returned on an er‐
       ror and buf is filled with a diagnostic.

       Getwd is in the style of 4.2 BSD and getcwd in that of  System  V.   If
       buf  is null, this entry will call malloc(3) to allocate size bytes for
       the buffer.
