typedef PRIntn (PR_CALLBACK *PLHashComparator)(
const void *v1,
const void *v2);
```
(plhashcomparator-description)=
## Description
{ref}`PLHashComparator` is a function type that compares two values of an
unspecified type. It returns a nonzero value if the two values are
equal, and 0 if the two values are not equal. {ref}`PLHashComparator`
defines the meaning of equality for the unspecified type.
For convenience, two comparator functions are provided.
{ref}`PL_CompareStrings` compare two character strings using `strcmp`.
{ref}`PL_CompareValues` compares the values of the arguments v1 and v2
numerically.

## Remark
The return value of {ref}`PLHashComparator` functions should be of type
{ref}`PRBool`.
