# Get QuickBlob here: https://github.com/keenerd/quickblob

# QuickBlob comes as a C library. To use it within your own
# program you need to implement a few functions:

# 
# QuickBlob comes with a command-line tool that depends on DevIL library
# but you are free to use your own image processor while integrating the
# library into your program.

Tokyo Cabinet B+ tree database

Overview

The Tokyo Cabinet B+tree database (a.k.a TCBDB) is implemented on-top of the hash database (TCHDB) that acts as the persistence layer.

Note: the same occurs with Tokyo table database (TCTDB) which is also a wrapper around the TCHDB (the table database can be thought as a document oriented database with querying capabilities).

Easy handle interface

Options

• CURLOPT_DNS_CACHE_TIMEOUT: controls the TTL of a DNS cache entry. The default is 60s. Use -1 to keep the entry forever.
• CURLOPT_RESOLVE: pre-populate the DNS cache manually.
• CURLOPT_DNS_SERVERS: use alternate DNS servers (instead of system default ones). Warning: works only with c-ares (and it requires c-ares version >= 1.7.4),
• CURLOPT_DNS_USE_GLOBAL_CACHE: cache DNS queries between easy handles. Warning: this is not thread-safe and documented as deprecated. Use the share interface instead (see below).
