C++ (Cpp) gzclearerr Examples

Example #1

File: zip-file.cpp Project: 191919/hhvm

bool ZipFile::seek(int64_t offset, int whence /* = SEEK_SET */) {
  assert(m_gzFile);

  if (whence == SEEK_CUR) {
    off_t result = gzseek(m_gzFile, 0, SEEK_CUR);
    if (result != (off_t)-1) {
      offset += result - (bufferedLen() + getPosition());
    }
    if (offset > 0 && offset < bufferedLen()) {
      setReadPosition(getReadPosition() + offset);
      setPosition(getPosition() + offset);
      return true;
    }
    offset += getPosition();
    whence = SEEK_SET;
  }

  // invalidate the current buffer
  setWritePosition(0);
  setReadPosition(0);
  setEof(false);
  gzclearerr(m_gzFile);
  flush();
  off_t result = gzseek(m_gzFile, offset, whence);
  setPosition(result);
  return result != (off_t)-1;
}

Example #2

File: IFile.cpp Project: jjmadsen/plumed2

void IFile::reset(bool reset){
 eof = reset;
 err = reset;
 if(!reset && fp) clearerr(fp);
#ifdef __PLUMED_HAS_ZLIB
 if(!reset && gzfp) gzclearerr(gzFile(gzfp));
#endif
 return;
}
