Functions

static INTVAL convert_flags_to_win32

Convert to platform-specific bit open flags.

INTVAL Parrot_io_init_win32

Sets up the standard std* IO handles.

INTVAL Parrot_io_getblksize_win32

Returns PIO_BLKSIZE.

PMC *Parrot_io_open_win32

Calls CreateFile() to open *spath with the Win32 translation of flags.

PMC *Parrot_io_fdopen_win32

Returns a new PMC with fd as its file descriptor.

INTVAL Parrot_io_close_win32

Calls CloseHandle() to close *io's file descriptor.

INTVAL Parrot_io_is_closed_win32

Test whether the filehandle has been closed.

static INTVAL io_is_tty_win32

Returns whether fd is a console/tty.

INTVAL Parrot_io_flush_win32

Calls FlushFileBuffers() to flush *io's file descriptor.

size_t Parrot_io_read_win32

Calls ReadFile() to read up to len bytes from *io's file descriptor to the memory starting at buffer.

size_t Parrot_io_write_win32

Calls WriteFile() to write len bytes from the memory starting at buffer to *io's file descriptor. Returns (size_t)-1 on failure.

PIOOFF_T Parrot_io_seek_win32

Hard seek.Calls SetFilePointer() to move the read/write position of *io's file descriptor to off bytes relative to the location specified by whence.

PIOOFF_T Parrot_io_tell_win32

Returns the current read/write position of *io's file descriptor.

size_t Parrot_io_peek_win32
