SYNOPSIS

       #include <libgearman/gearman.h>

       Link -lgearman

DESCRIPTION

       Gearman  Client/Worker  Library  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.

       PKG_CHECK_MODULES(DEPS, libgearman >= 0.8.0) AC_SUBST(DEPS_CFLAGS) AC_SUBST(DEPS_LIBS)

       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.
