CPU_DB_TaskID CPU_DB_getTaskID

(

const char *

name

)

Return the (CPU_DB) task ID for the task with the given name.

Parameters:

name

Task name (as it appears in the CPU_DB task table)

Return values:

	x	Task ID (from CPU_DB enumeration)
	0	No task ID found

CPU_DB_getTaskID() returns a the task ID (from the CPU_DB enumeration) for the task with task name "name". If the name can't be found, the value zero (the "anonymous" task) is returned.

References _CPU_DB_TaskAttr::ID, _CPU_DB_TaskAttr::name, and _CPU_DB_Schema::taskList.

const char * CPU_DB_getTaskName

(

CPU_DB_TaskID

tid

)

Return a pointer to the task name for a given task ID.

Parameters:

tid

Task ID (from CPU_DB enumeration)

Return values:

	x	Pointer to task name
	NULL	No task name found

CPU_DB_getTaskName() returns a pointer to a task name for the given task ID NULL is returned if the task ID cannot be found.

References _CPU_DB_TaskAttr::ID, _CPU_DB_TaskAttr::name, and _CPU_DB_Schema::taskList.

int CPU_DB_getTaskPriority

(

CPU_DB_TaskID

tid

)

Return the task priority for a given task ID.

Parameters:

tid

Task ID (from CPU_DB enumeration)

Return values:

	-1	Task priority not found
	x	Task priority

CPU_DB_getTaskPriority() returns the task priority for a given task ID. If a task priority cannot be found, -1 is returned.

References _CPU_DB_TaskAttr::ID, _CPU_DB_TaskAttr::priority, and _CPU_DB_Schema::taskList.

CPU_DB_Type CPU_DB_getType

(

void

)

Return the CPU type (SIU, EPU, or SC) as recorded in the CPU database.

Return values:

	CPU_DB_TYPE_NONE	Could not identify CPU type (missing database?)
	CPU_DB_TYPE_SIU	SIU
	CPU_DB_TYPE_EPU	EPU
	CPU_DB_TYPE_SC	SC

CPU_DB_getType() returns the type of the calling CPU, as recorded in the CPU database. Intended as a cross-check to avoid the situation where the database specific to one type of CPU is accidentally loaded on another.
