dacs_runtime_init

NAME

dacs_runtime_init - Initialize all runtime services for DaCS.

SYNOPSIS

DACS_ERR_T dacs_runtime_init ( void *, void * )

Call parameters
All parameters must be set to NULL for SDK 3.0. Passing in a value other than NULL will result in the error DACS_ERR_INVALID_ADDR.

DESCRIPTION

The dacs_runtime_init service initializes all runtime services for DaCS.
Note: This service must be called for every process before any other DaCS services can be used. All other DaCS services will return DACS_ERR_NOT_INITIALIZED if called before this service.
A host process may call this service more than once, provided there is a call to dacs_runtime_exit() in between. An accelerator process may only call this service once, even if there is an intervening call to dacs_runtime_exit().

RETURN VALUE

The dacs_runtime_init service returns an error indicator defined as:
  • DACS_SUCCESS: normal return.
  • DACS_ERR_INVALID_ADDR: invalid pointer.
  • DACS_ERR_NO_RESOURCE: unable to allocate required resources.
  • DACS_ERR_INITIALIZED: DaCS is already initialized.
