How to change buffer size?

[blnked]

Any way to change buffer size (existing buffer)

thanks

[blnked]

found one way but I'm not sure that optimal way

bufferSize = 'new buffer size';

int32_t availableToReadBytes;
uint8_t *tempBuffer = TPCircularBufferTail(&buffer, &availableToReadBytes);
printf("+ availableToReadBytes %d \n", availableToReadBytes);

SInt16 *newBuffer = (SInt16*)malloc(sizeof(SInt16)*availableToReadBytes);
memcpy(newBuffer, tempBuffer, availableToReadBytes);

TPCircularBufferCleanup(&buffer);

TPCircularBufferInit(&buffer, bufferSize);

TPCircularBufferProduceBytes(&buffer, newBuffer, availableToReadBytes);
printf("buffer size was changed on %d \n", bufferSize);

// check how many bytes is available
int32_t bytesToRead;
TPCircularBufferTail(&buffer, &bytesToRead);
printf("+ bytesToRead %d \n", availableToReadBytes);

One warning - if you're doing this on the fly, manipulating the buffer like that kinda breaks it's thread-safeness. Unless this isn't on the fly and you're not using it at the time you're resizing - then that's okay.

quick note for who are trying to do something similar

please review your app architecture again. probably you won't to think in future that buffer size changing is a good idea. I hope that's help you keep time.
