GEARMAN_CLIENT_DO_LOW(3)					     Gearmand						  GEARMAN_CLIENT_DO_LOW(3)

NAME

       gearman_client_do_low - Gearmand Documentation, http://gearman.info/

SYNOPSIS

       #include <libgearman/gearman.h>

       void  *gearman_client_do(gearman_client_st *client,  const  char *function_name,  const	char *unique,  const  void *workload, size_t work-
       load_size, size_t *result_size, gearman_return_t *ret_ptr)

       Changed in version 0.21: GEARMAN_PAUSE will no longer be returned. A do operation will now run till completion or error.

       void *gearman_client_do_high(gearman_client_st *client, const char *function_name, const char *unique, const  void *workload,  size_t work-
       load_size, size_t *result_size, gearman_return_t *ret_ptr)

       void  *gearman_client_do_low(gearman_client_st *client,	const  char *function_name, const char *unique, const void *workload, size_t work-
       load_size, size_t *result_size, gearman_return_t *ret_ptr)

DESCRIPTION

       gearman_client_do() executes a single request to the gearmand server and waits for a reply.

       gearman_client_do_high() and gearman_client_do_low() are identical to gearman_client_do(), only they set the priority  to  either  high	or
       low.

       All of the functions will block until either a response or an error is returned.

RETURN VALUE

       gearman_client_do() returns a pointer to a value that the caller must release. If ret_ptr is provided any errors that have occurred will be
       stored in it. Since a NULL/zero value is a valid value, you will always need to check ret_ptr if you are concerned with errors.

EXAMPLE

       #include <string.h>
       #include <stdlib.h>
       #include <libgearman/gearman.h>

       int main(void)
       {
	 gearman_client_st *client= gearman_client_create(NULL);

	 gearman_return_t ret= gearman_client_add_server(client, "localhost", 0);
	 if (gearman_failed(ret))
	 {
	   return EXIT_FAILURE;
	 }

	 size_t result_size;
	 gearman_return_t rc;
	 void *value= gearman_client_do(client, "reverse_function", "unique_value",
					"my string to reverse", strlen("my string to reverse"),
					&result_size, &rc);

	 if (gearman_success(rc))
	 {
	   // Make use of value
	 }
	 free(value);

	 gearman_client_free(client);

	 return 0;
       }
