Comparison of integer expressions of different signedness

[sounddroid]

Hello! Using gcc 9.1.0, I'm getting a few compiler warnings:

In reader.hpp:

Line 220:
if (frameOffset < 0 && dataChunkOffset < -frameOffset) {
*warning: comparison of integer expressions of different signedness: 'uint64_t' {aka 'long unsigned int'} and 'int64_t' {aka 'long int'} [-Wsign-compare]

Line 225:
if (fileStream_.tellg() < chunkPosition) {
*warning: comparison of integer expressions of different signedness: 'std::streamoff' {aka 'long int'} and 'uint64_t' {aka 'long unsigned int'} [-Wsign-compare]

Line 227:
} else if (fileStream_.tellg() > chunkPosition + dataChunk()->size()) {
*comparison of integer expressions of different signedness: 'std::streamoff' {aka 'long int'} and 'uint64_t' {aka 'long unsigned int'} [-Wsign-compare]

Any chance that this can get looked at and addressed safely?

This should fix them:

if (frameOffset < 0 && dataChunkOffset < static_cast<uint64_t>(-frameOffset)) {

and

const auto fileStreamPos = fileStream_.tellg();
if (fileStreamPos < 0)
  throw std::runtime_error("fileStream::tellg failed");
if (static_cast<uint64_t>(fileStreamPos) < chunkPosition) {
  fileStream_.seekg(chunkPosition);
} else if (static_cast<uint64_t>(fileStreamPos) > chunkPosition + dataChunk()->size()) {
  fileStream_.seekg(chunkPosition + dataChunk()->size());
}
