YY_BUFFER_STATE cframe_create_buffer (  FILE *  file,
int  size
) 
 

void cframe_delete_buffer (  YY_BUFFER_STATE  b  ) 
 

void cframe_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.

Definition at line 1276 of file cframe_lexer.c.

References yy_buffer_state::yy_at_bol, yy_buffer_state::yy_buf_pos, yy_buffer_state::yy_buffer_status, yy_buffer_state::yy_ch_buf, and yy_buffer_state::yy_n_chars.

YY_BUFFER_STATE cframe_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.

Here is the call graph for this function:

YY_BUFFER_STATE cframe_scan_bytes (  yyconst char *  yybytes,
int  _yybytes_len
) 
 

Setup the input buffer state to scan the given bytes. The next call to cframelex() 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.

Here is the call graph for this function:

YY_BUFFER_STATE cframe_scan_string (  yyconst char *  yystr  ) 
 

Setup the input buffer state to scan a string. The next call to cframelex() 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 cframe_scan_bytes() instead.
