PLHashComparator¶
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.
