## Syntax
|
|
|
|
```{code}
|
|
#include <plhash.h>
|
|
|
|
typedef PRIntn (PR_CALLBACK *PLHashComparator)(
|
|
const void *v1,
|
|
const void *v2);
|
|
```

|
## 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`.
