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; }
