getcwd(3C) — sys5



GETCWD(3C)      DOMAIN/IX Reference Manual (SYS5)      GETCWD(3C)



NAME
     getcwd - get pathname of current working directory

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

DESCRIPTION
     Getcwd returns a pointer to the current directory pathname.
     The value of size must be at least two characters larger
     than the length of the pathname that the function returns.

     If buf is a NULL pointer, getcwd will obtain size bytes of
     space using malloc(3C).  In this case, the pointer returned
     by getcwd can be used as the argument in a subsequent call
     to free.

EXAMPLE
          char *cwd, *getcwd();
          .
          .
          .
          if ((cwd = getcwd((char *)NULL, 64)) == NULL) {
               perror(``pwd'');
               exit(1);
          }
          printf(``%s\n'', cwd);

DIAGNOSTICS
     Returns NULL with errno set if size is not large enough, or
     if an error occurs in a lower-level function.
