# bson\_compare(3)

## SYNOPSIS

```
int
bson_compare (const bson_t *bson, const bson_t *other);
```

## PARAMETERS

- •

  **bson**: A *bson\_t*.

- •

  **other**: A *bson\_t*.

## DESCRIPTION

The *bson\_compare()* function shall compare two bson documents for equality.

This can be useful in conjunction with \_qsort()\_.

If equal, 0 is returned.

**TIP:**

This function uses \_memcmp()\_ internally, so the semantics are the same.

## RETURNS

less than zero, zero, or greater than zero in **qsort()** style.
