YY_BUFFER_STATE do_create_buffer	(	FILE *	file,
		int	size
	)

void do_delete_buffer ( YY_BUFFER_STATE b )

void do_flush_buffer ( YY_BUFFER_STATE b )

Discard all buffered characters. On the next scan, YY_INPUT will be called.

Parameters:

b the buffer state to be flushed, usually YY_CURRENT_BUFFER.

References yy_buffer_state::yy_at_bol, yy_buffer_state::yy_buf_pos, YY_BUFFER_NEW, yy_buffer_state::yy_buffer_status, yy_buffer_state::yy_ch_buf, YY_CURRENT_BUFFER, YY_END_OF_BUFFER_CHAR, and yy_buffer_state::yy_n_chars.

YY_BUFFER_STATE do_scan_buffer	(	char *	base,
		yy_size_t	size
	)

Setup the input buffer state to scan directly from a user-specified character buffer.

Parameters:

	base	the character buffer
	size	the size in bytes of the character buffer

Returns:: the newly allocated buffer state object.

YY_BUFFER_STATE do_scan_bytes	(	yyconst char *	bytes,
		int	len
	)

Setup the input buffer state to scan the given bytes. The next call to dolex() will scan from a copy of bytes.

Parameters:

	yybytes	the byte buffer to scan
	_yybytes_len	the number of bytes in the buffer pointed to by bytes.

Returns:: the newly allocated buffer state object.

YY_BUFFER_STATE do_scan_string ( yyconst char * yy_str )

Setup the input buffer state to scan a string. The next call to dolex() will scan from a copy of str.

Parameters:

yystr

a NUL-terminated string to scan

Returns:: the newly allocated buffer state object.

Note:: If you want to scan bytes that may contain NUL values, then use do_scan_bytes() instead.

int doget_debug ( void )

YY_EXTRA_TYPE doget_extra ( void )

FILE* doget_in ( void )

Get the input stream.

References doin.

int doget_leng ( void )

Get the length of the current token.

int dolex_destroy ( void )

References do_delete_buffer(), dofree(), dopop_buffer_state(), YY_CURRENT_BUFFER, and YY_CURRENT_BUFFER_LVALUE.

void dopop_buffer_state ( void )

Removes and deletes the top of the stack, if present. The next element becomes the new top.

void dopush_buffer_state ( YY_BUFFER_STATE new_buffer )

Pushes the new state onto the stack. The new state becomes the current state. This function will allocate the stack if necessary.

Parameters:

new_buffer

The new state.

void dorestart ( FILE * input_file )

void doset_debug ( int debug_flag )

void doset_extra ( YY_EXTRA_TYPE user_defined )

void doset_in ( FILE * in_str )

Set the input stream. This does not discard the current input buffer.

Parameters:

in_str

A readable stream.

void doset_lineno ( int line_number )

Set the current line number.

Parameters:

line_number
