NAME
       libgearman - Gearmand Documentation, http://gearman.info/

SYNOPSIS
       #include <libgearman/gearman.h>

       Link -lgearman

DESCRIPTION
       libgearman is a small, thread-safe client library for the gearman
       protocol. The code has all been written with an eye to allow for both
       web and embedded usage. It handles the work behind routing particular
       keys to specific servers that you specify (and values are matched based
       on server order as supplied by you). It implements both the client and
       worker interfaces.

       All operations are performed against either a client, ie
       gearman_client_st or worker, ie gearman_worker_st.

       Client and Worker structures can either be dynamically allocated or
       statically allocated. They must then b initialized by
       gearman_client_create() or gearman_worker_create().

       Functions have been written in order to encapsulate all structures in
       the library. It is recommended that you do not operate directly against
       the structure.

       Nearly all functions return a gearman_return_t value.  This value can
       be translated to a printable string with gearman_strerror().

       gearman_client_st and gearman_worker_st structures are thread-safe, but
       each thread must contain its own structure (that is, if you want to
       share these among threads you must provide your own locking). No global
       variables are used in this library.

       If you are working with GNU autotools you will want to add the
       following to your configure.ac to properly include libgearman in your
       application.

       Hope you enjoy it!

CONSTANTS
       A number of constants have been provided for in the library.

       GEARMAN_DEFAULT_TCP_PORT

       The default port used by gearmand(3).

       GEARMAN_DEFAULT_TCP_PORT

       The default service used by gearmand(3).

       LIBGEARMAN_VERSION_STRING

       String value of the libgearman version such as "0.20.4"

       LIBGEARMAN_VERSION_HEX

       Hex value of the version number. "0x00048000" This can be used for
       comparing versions based on number.

       GEARMAN_UNIQUE_SIZE

       Largest number of characters that can be used for a unique value.

       GEARMAN_JOB_HANDLE_SIZE

       Largest number of characters that can will be used for a job handle.
       Please see gearman_job_handle_t for additional information.

THREADS AND PROCESSES
       When using threads or forked processes it is important to keep an
       instance of gearman_client_st or gearman_worker_st  per process or
       thread.  Without creating your own locking structures you can not share
       a single gearman_client_st or gearman_worker_st.
