tccb_add_dcw - add a dcw to the tccb : the tccb address : the maximum tccb size : the dcw command : flags for the dcw : pointer to control data for this dcw or NULL if none is required : number of control data bytes for this dcw : number of data bytes for this dcw
Add a new dcw to the specified tccb by writing the dcw information specified by , , , and to the tca of the tccb. Return a pointer to the newly added dcw on success or -ENOSPC if the new dcw would exceed the available space as defined by .
Note: the tcal field of the tccb header will be updates to reflect added content.
Definition at line 294 of file fcx.c.
tccb_init - initialize tccb : the tccb address : the maximum size of the tccb : the service-action-code to be user
Initialize the header of the specified tccb by resetting all values to zero and filling in defaults for format, sac and initial tcal fields.
Definition at line 255 of file fcx.c.
tcw_add_tidaw - add a tidaw to a tcw : the tcw address : the current number of tidaws : flags for the new tidaw : address value for the new tidaw : count value for the new tidaw
Add a new tidaw to the input/output data tidaw-list of the specified tcw (depending on the value of the r-flag and w-flag) and return a pointer to the new tidaw.
Note: the tidaw-list is assumed to be contiguous with no ttics. The caller must ensure that there is enough space for the new tidaw. The last-tidaw flag for the last tidaw in the list will be set by tcw_finalize.
Definition at line 337 of file fcx.c.
tcw_finalize - finalize tcw length fields and tidaw list : pointer to the tcw : the number of tidaws used to address input/output data or zero if no tida is used
Calculate the input-/output-count and tccbl field in the tcw, add a tcat the tccb and terminate the data tidaw list if used.
Note: in case input- or output-tida is used, the tidaw-list must be stored in contiguous storage (no ttic). The tcal field in the tccb must be up-to-date.
Definition at line 152 of file fcx.c.
tcw_get_data - return pointer to input/output data associated with tcw : pointer to the tcw
Return the input or output data address specified in the tcw depending on whether the r-bit or the w-bit is set. If neither bit is set, return NULL.
Definition at line 38 of file fcx.c.
tcw_get_intrg - return pointer to associated interrogate tcw : pointer to the original tcw
Return a pointer to the interrogate tcw associated with the specified tcw or NULL if there is no associated interrogate tcw.
Definition at line 24 of file fcx.c.
tcw_init - initialize tcw data structure : pointer to the tcw to be initialized : initial value of the r-bit : initial value of the w-bit
Initialize all fields of the specified tcw data structure with zero and fill in the format, flags, r and w fields.
Definition at line 81 of file fcx.c.
tcw_set_data - set data address and tida flag of a tcw : the tcw address : the data address : zero of the data address specifies a contiguous block of data, non-zero if it specifies a list if tidaws.
Set the input/output data address of a tcw (depending on the value of the r-flag and w-flag). If is non-zero, the corresponding tida flag is set as well.
Definition at line 206 of file fcx.c.
tcw_set_intrg - set the interrogate tcw address of a tcw : the tcw address : the address of the interrogate tcw
Set the address of the interrogate tcw in the specified tcw.
Definition at line 189 of file fcx.c.
tcw_set_tccb - set tccb address of a tcw : the tcw address : the tccb address
Set the address of the tccb in the specified tcw.
Definition at line 227 of file fcx.c.
tcw_set_tsb - set tsb address of a tcw : the tcw address : the tsb address
Set the address of the tsb in the specified tcw.
Definition at line 240 of file fcx.c.
tsb_init - initialize tsb : the tsb address
Initialize the specified tsb by resetting all values to zero.
Definition at line 270 of file fcx.c.
