Syntax

#include <plhash.h>

typedef PRIntn (PR_CALLBACK *PLHashComparator)(
  const void *v1,
  const void *v2);

Description

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. PLHashComparator defines the meaning of equality for the unspecified type.

For convenience, two comparator functions are provided. PL_CompareStrings compare two character strings using strcmp. PL_CompareValues compares the values of the arguments v1 and v2 numerically.

Remark

The return value of PLHashComparator functions should be of type PRBool.
