Function Documentation

int check_expiration (  struct PINT_tcache *  tcache, struct PINT_tcache_entry *  entry, struct timeval *  tv )  [static]

time interval to check expiration against Parameters: entry  tcached entry

int tcache_lookup_oldest (  struct PINT_tcache *  tcache, struct PINT_tcache_entry **  entry, int *  status )  [static]

indicates if the entry is expired or not Subsequent tcache function calls may destroy the entry and payload. Therefore the caller should copy the payload data if it intends to use it after another tcache function call. Returns: 0 on success, -PVFS_error on failure Parameters: tcache  pointer to tcache instance entry  tcache entry (output) status  indicates if the entry is expired or not

Here is the call graph for this function:
