Error Handling

The following error states can be returned by the rtld-debugger interface (defined in rtld_db.h).

typedef enum {
        RD_ERR,
        RD_OK,
        RD_NOCAPAB,
        RD_DBERR,
        RD_NOBASE,
        RD_NODYNAM,
        RD_NOMAPS
} rd_err_e;

The following interfaces can be used to gather the error information.

rd_errstr()

This function returns a descriptive error string describing the error code rderr.

char *rd_errstr(rd_err_e rderr);

rd_log()

This function turns logging on (1) or off (0).

void rd_log(const int onoff);

When logging is turned on, the imported interface function ps_plog() provided by the controlling process, is called with more detailed diagnostic information.
