cygwin_conv_path(3)

NAME
cygwin_conv_path

SYNOPSIS
extern "C" ssize_t
cygwin_conv_path (cygwin_conv_path_t what, const void * from, void * to, size_t size);

DESCRIPTION
Use this function to convert POSIX paths in from to Win32 paths in toor, vice versa, Win32 paths in from to POSIX paths in to. whatdefines the direction of this conversion and can be any of the below values. CCP_POSIX_TO_WIN_A /* from is char *posix, to is char *win32 */ CCP_POSIX_TO_WIN_W, /* from is char *posix, to is wchar_t *win32 */ CCP_WIN_A_TO_POSIX, /* from is char *win32, to is char *posix */ CCP_WIN_W_TO_POSIX, /* from is wchar_t *win32, to is char *posix */ You can additionally or the following values to what, to define whether you want the resulting path in to to be absolute or if you want to keep relative paths in relative notation. Creating absolute paths is the default. CCP_ABSOLUTE = 0, /* Request absolute path (default). */ CCP_RELATIVE = 0x100 /* Request to keep path relative. */ size is the size of the buffer pointed to by to in bytes. If sizeis 0, cygwin_conv_path ( just returns the required buffer size in bytes. Otherwise, it returns 0 on success, or -1 on error and errno is set to one of the below values. EINVAL what has an invalid value. EFAULT from or to point into nirvana. ENAMETOOLONG the resulting path is longer than 32K, or, in case of what == CCP_POSIX_TO_WIN_A, longer than MAX_PATH. ENOSPC size is less than required for the conversion.

EXAMPLE
/* Conversion from incoming Win32 path given as wchar_t *win32 to POSIX path.
   If incoming path is a relative path, stick to it. First ask how big
   the output buffer has to be and allocate space dynamically. */
ssize_t size;
char *posix;
size = cygwin_conv_path (CCP_WIN_W_TO_POSIX | CCP_RELATIVE, win32, NULL, 0);
  perror ("cygwin_conv_path");
else
  {
    posix = (char *) malloc (size);
    if (cygwin_conv_path (CCP_WIN_W_TO_POSIX | CCP_RELATIVE, win32,
                        posix, size))
      perror ("cygwin_conv_path");
