== Getting startup data ==

The following functions return startup data:

{{{
#!c++
int boinc_get_init_data_p(APP_INIT_DATA*);
int boinc_get_init_data(APP_INIT_DATA&);

struct APP_INIT_DATA {
    int major_version;          // BOINC client version info
    int minor_version;
    int release;
    int app_version;
    char app_name[256];
    char symstore[256];         // symstore URL (Windows)
    char acct_mgr_url[256];
        // if client is using account manager, its URL
    char* project_preferences;
        // project prefs XML
    int userid;
        // project's DB ID for this user/team/host
    int teamid;
    int hostid;
    char user_name[256];
    char team_name[256];

    char result_name[256];
    char authenticator[256];    // user's authenticator
    int slot;                   // the slot this job is running in (0, 1, ...)

};

== Getting runtime system status ==

The status of the runtime system is represented by the following structure:
{{{
typedef struct BOINC_STATUS {
    int no_heartbeat;
    int suspended;
    int quit_request;
    int reread_init_data_file;
    int abort_request;
    double working_set_size;
    double max_working_set_size;
    int network_suspended;
} BOINC_STATUS;
}}}

 '''no_heartbeat''':: no heartbeat from client; clean up and exit(0).
 '''suspended''':: the client has requested that we suspend ourself.
 '''quit_request''':: the client has requested that we exit (will restart).
 '''reread_init_data_file''': project preferences have changed; reread them if needed.
 '''abort_request''': the client has request that we abort (no restart).
 '''working_set_size''':: our current working-set size
 '''max_working_set_size''':: the amount of available RAM
 '''network_suspended''':: set of network activity is not currently allowed

You can get the current status using

{{{
void boinc_get_status(BOINC_STATUS*);
}}}
