Function Documentation

void tidyBufInit (  TidyBuffer *    buf )

Zero out data structure

void tidyBufAlloc (  TidyBuffer *    buf, uint    allocSize )

Free current buffer, allocate given amount, reset input pointer

void tidyBufCheckAlloc (  TidyBuffer *    buf, uint    allocSize, uint    chunkSize )

Expand buffer to given size. Chunk size is minimum growth. Pass 0 for default of 256 bytes.

void tidyBufFree (  TidyBuffer *    buf )

Free current contents and zero out

void tidyBufClear (  TidyBuffer *    buf )

Set buffer bytes to 0

void tidyBufAttach (  TidyBuffer *    buf, void *    bp, uint    size )

Attach to existing buffer

void tidyBufDetach (  TidyBuffer *    buf )

Detach from buffer. Caller must free.

void tidyBufAppend (  TidyBuffer *    buf, void *    vp, uint    size )

Append bytes to buffer. Expand if necessary.

void tidyBufPutByte (  TidyBuffer *    buf, byte    bv )

Append one byte to buffer. Expand if necessary.

int tidyBufPopByte (  TidyBuffer *    buf )

Get byte from end of buffer

int tidyBufGetByte (  TidyBuffer *    buf )

Get byte from front of buffer. Increment input offset.

Bool tidyBufEndOfInput (  TidyBuffer *    buf )

At end of buffer?

void tidyBufUngetByte (  TidyBuffer *    buf, byte    bv )

Put a byte back into the buffer. Decrement input offset.

void initInputBuffer (  TidyInputSource *    inp, TidyBuffer *    buf )

Initialize a buffer input source

void initOutputBuffer (  TidyOutputSink *    outp, TidyBuffer *    buf )

Initialize a buffer output sink
