Function Documentation

YY_BUFFER_STATE yy_create_buffer ( FILE *  file,
int  size 
)

void yy_delete_buffer ( YY_BUFFER_STATE  b  ) 

void yy_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.

YY_BUFFER_STATE yy_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 yy_scan_bytes ( yyconst char *  yybytes,
int  _yybytes_len 
)

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

Parameters:
bytes the byte buffer to scan
len the number of bytes in the buffer pointed to by bytes.
Returns:
the newly allocated buffer state object.

YY_BUFFER_STATE yy_scan_string ( yyconst char *  yystr  ) 

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

Parameters:
str 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 yy_scan_bytes() instead.

void yy_switch_to_buffer ( YY_BUFFER_STATE  new_buffer  ) 

void * yyalloc ( yy_size_t  size  ) 

void yyfree ( void *  ptr  ) 

int yyget_debug ( void   ) 

FILE* yyget_in ( void   ) 

Get the input stream.

int yyget_leng ( void   ) 

Get the length of the current token.

int yyget_lineno ( void   ) 

Get the current line number.

FILE* yyget_out ( void   ) 

Get the output stream.

char* yyget_text ( void   ) 

Get the current token.

int yylex_destroy ( void   ) 

void yypop_buffer_state ( void   ) 

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

void yypush_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 * yyrealloc ( void *  ptr,
yy_size_t  size 
)

void yyrestart ( FILE *  input_file  ) 

void yyset_debug ( int  bdebug  ) 

void yyset_in ( FILE *  in_str  ) 

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

Parameters:
in_str A readable stream.
See also:
yy_switch_to_buffer

void yyset_lineno ( int  line_number  ) 

Set the current line number.

Parameters:
line_number 

void yyset_out ( FILE *  out_str  )
