Member Function Documentation

void Console_buffer::alloc (  size_t  size  )  [static]

Allocates a buffer of the given size. Parameters: size  the buffer size in bytes.

void Console_buffer::at_jdb_enter (   )  [static, private]

void Console_buffer::at_jdb_leave (   )  [static, private]

void Console_buffer::dec_out_ptr (  char **  c  )  [inline, static, private]

Mword Console_buffer::get_attributes (   )  const [virtual]

Console attributes. Reimplemented from Console.

int Console_buffer::getchar (  bool   )  [virtual]

read a charcater from the input. Parameters: blocking  if true getchar blocks til a charcater is available. This method must be implemented in every implementation, but can simply return -1 for output only consoles. Reimplemented from Console.

void Console_buffer::inc_ptr (  char **  c  )  [inline, static, private]

FIASCO_INIT void Console_buffer::init (   )  [static]

int Console_buffer::print_buffer (  const char *  str  )  [static]

Prints the buffer to the standard I/O. Parameters: str  the string the output should be filtered for This method prints the buffer contents to the normal I/O. Before doing this the buffer is disabled, that no recursion appers even if the buffer is part of the muxed I/O.

int Console_buffer::print_buffer (  unsigned  lines  )  [static]

Prints the buffer to the standard I/O. Parameters: lines  the number of lines to skip. This method prints the buffer contents to the normal I/O. Before doing this the buffer is disabled, that no recursion appers even if the buffer is part of the muxed I/O.

int Console_buffer::strncmp (  char *  start, const char *  search, size_t  len )  [static, private]

int Console_buffer::write (  char const *  str, size_t  len )  [virtual]

Write a string of len chacters to the output. Parameters: str  the string to write (no zero termination is needed) len  the number of chacters to write. This method must be implemented in every implementation, but can simply do nothing for input only consoles. Reimplemented from Console.
