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
.
