DESCRIPTION

The bson_reader_read(3) function shall read the next document from the underlying file-descriptor or buffer.

If we reached the end of the sequence, reached_eof is set to true.

To detect an error, check for NULL and reached_of is false.

EXAMPLE

const bson_t *doc;
bool reached_eof = false;

while ((doc = bson_reader_read (reader, &reached_eof))) {

}

if (!reached_eof) {
        fprintf (stderr, "Failed to read all documents.\n");
}
