GEARMAN_CLIENT_DO(3) Gearmand GEARMAN_CLIENT_DO(3)NAMEgearman_client_do - Gearmand Documentation, http://gearman.info/
SYNOPSIS
#include <libgearman/gearman.h>
void *gearman_client_do(gearman_client_st *client, const char *func‐
tion_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 workload_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 workload_size, size_t *result_size, gearman_return_t *ret_ptr)
DESCRIPTIONgearman_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 VALUEgearman_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.
