How do I get binary data from pdf created in libharu?

I have a basic C function, which creates a pdf and then writes it to the disc with HPDF_SaveToFile(pdf, filename) where pdf is an instance of HPDF_Doc.

But now I want to change the function behaviour so instead of writing to disc, it would return pdf as binary, which I will work with elsewhere.

How do I get binary from HPDF_Doc variable?

Solution

  • Solved, here's how I did it: 

    HPDF_SaveToStream(pdf);
unsigned int streamSize = HPDF_GetStreamSize(pdf);
unsigned char* buffer = malloc(streamSize * sizeof(buffer));
HPDF_Stream_Read(pdf->stream, buffer, &streamSize);

    this way buffer variable will contain the binary
