Help plz
Does any one have any idea how to compare interval ranges of 2 files.
finding 1-4 (1,2,3,4) of input2 in input1 of same key "a" values (5-10, 30-40, 45-60, 80-90, 100-120 ). Obviously 1-4 is not one of the range with in input1 a. so it should give out of range.
finding 30-33(31,32,33)... (1 Reply)

cache_get_and_retain
cache_set_and_retain(3) BSD Library Functions Manual cache_set_and_retain(3)NAME
cache_set_and_retain, cache_get_and_retain, cache_release_value, cache_remove -- Routines used to manage cached values
SYNOPSIS
#include <cache.h>
int
cache_set_and_retain(cache_t *cache, void *key, void *value, size_t cost);
int
cache_get_and_retain(cache_t *cache, void *key, void **value_out);
int
cache_release_value(cache_t *cache, void *value);
int
cache_remove(cache_t *cache, void *key);
DESCRIPTION
These routines are used to manipulate values added to an in memory cache created by cache_create(3).
cache_set_and_retain() Adds value with cost to cache and associates it with key. The caller retains a reference to value that will prevent
value from being evicted from the cache until value is released in cache_release_value().
cache_get_and_retain() Fetches value for key from cache and places value in value_out. The caller retains a reference to value that will
prevent value from being evicted from the cache until value is release in cache_release_value().
cache_release_value() Releases a reference on value back to cache so that value may be evicted. Signals that the client is not actively
using value and will use cache_get_and_retain() before using again.
cache_remove() Removes the value associated with key from cache. Note that if the value is referenced by a client, the value will not be
finalized until the reference is released using cache_release_value().
RETURN VALUES
All functions return 0 for success and non-zero for failure. The value ENOENT (see errno.h) indicates that a key or value passed as an argu-
ment does not exist in the cache. EINVAL is used for invalid arguments.
EXAMPLE
The following example attempts to fetch a value from a cache using a key. If the value is not present in the cache then it is created and
added to the cache. The value is then used and released back to the cache to allow the cache to evict it when needed.
cache_t *mycache;
cache_create("com.mycompany.mycache", &cache_attributes, &mycache);
void *mykey = my_create_key();
void *myvalue = NULL;
if (cache_get_and_retain(mycache, mykey, &myvalue) != 0) {
myvalue = my_create_value_from_key(mykey);
cache_set_and_retain(mycache, mykey, myvalue, 0);
}
my_use_value(value);
cache_release_value(mycache, myvalue);
