Functions

static int cmp_key_string (union HashKey a, union HashKey b)
 Compare two string keys - Implements hash_cmp_key_t -.
 
static int cmp_key_case_string (union HashKey a, union HashKey b)
 Compare two string keys (ignore case) - Implements hash_cmp_key_t -.
 
static int cmp_key_int (union HashKey a, union HashKey b)

Detailed Description

Prototype for a function to compare two Hash keys.

Parameters
aFirst key to compare
bSecond key to compare
Return values
-1a precedes b
0a and b are identical
1b precedes a

This works like strcmp().
