NAME

lcg_set_transfer_callback - Get/Set the pointer of the transfer file callback

SYNOPSIS

#include "lcg_util.h"

void lcg_set_transfer_callback (copyfile_callback_t *cb);

copyfile_callback_t lcg_get_transfer_callback ();

DESCRIPTION

lcg_set_transfer_callback sets the pointer of the transfer file callback

cb

specifies the pointer to the desired function.

    typedef struct {
        GFAL_LONG64 transferred_bytes;

        float instant_throughput;

        float avg_throughput;

    } perf_t;

    typedef void (* copyfile_callback_t) (
        perf_t                  s_perf,

        struct  timespec        ts,

        int                     *timeoutflg

        );

EXAMPLE

Here is the function which is used in verbose mode:

    void copy_print_callback(perf_t perf, struct timespec ts, int *timeoutflg) {
        fprintf(stderr,"\r %12lld bytes", (GFAL_LONG64)perf.transferred_bytes);
        fprintf(stderr," %9.2lf KB/sec avg", (double)perf.avg_throughput/1024);
        fprintf(stderr," %9.2lf KB/sec inst", (double)perf.instant_throughput/1024);
    }
