typedef struct wl_type

Workload type descriptor

Set up it statically in your module

MEMBERS

• wlt_name - Name of workload type (use AAS_CONST_STR for it)
  
• wlt_class - Bitmask of workload class flags
  
• wlt_description - Description of a workload type
  
• wlt_params - pointer to a vector of workload/request parameter descriptors
  
• wlt_params_size - sizeof() of workload parameters structure
  
• wlt_rqparams_size - sizeof() of request parameters structure
  
• wlt_wl_config - pointer to function that configures workload
  
• wlt_wl_unconfig - pointer to function that destroyes worklaod
  
• wlt_wl_step - function that will be called at beginning of each step
  
• wlt_run_request - primary workload function that services request
  
• wlt_module - should be set to module structure passed to mod_config()
  
• wlt_next - field internally used by TSLoad, set to NULL
