#include <sys/cygwin.h>

cygwin_conv_path_list(cygwin_conv_path_t what, const void * from, void * to, size_t size);
This is the same as cygwin_conv_path, but the
input is treated as a path list in $PATH or %PATH% notation.
If what is CCP_POSIX_TO_WIN_A or
CCP_POSIX_TO_WIN_W, given a POSIX $PATH-style string (i.e. /foo:/bar)
convert it to the equivalent Win32 %PATH%-style string (i.e. d:\;e:\bar).
If what is CCP_WIN_A_TO_POSIX or
CCP_WIN_W_TO_POSIX, given a Win32 %PATH%-style string (i.e. d:\;e:\bar)
convert it to the equivalent POSIX $PATH-style string (i.e. /foo:/bar).
size is the size of the buffer pointed to by
to in bytes.
