td_set_reg
Set Task Register
See Also
[C Language Interface]
ER ercd = td_set_reg ( ID tskid, T_REGS *pk_regs, T_EIT *pk_eit, T_CREGS *pk_cregs ) ;
[Parameters]
ID tskid Task ID (TSK_SELF cannot be specified)
T_REGS* pk_regs General registers
T_EIT* pk_eit Registers saved when exception is raised
T_CREGS* pk_cregs Control registers
The contents of T_REGS, T_EIT, and T_CREGS are defined for each CPU and implementation.
[Return Parameters]
ER ercd Error code
[Error Codes]
E_OK Normal completion
E_ID Invalid ID number (tskid is invalid or cannot be used)
E_NOEXS Object does not exist (the task designated in tskid does not exist)
E_OBJ Invalid object state (issued for current RUN state task)
[Description]
Sets registers of the task designated in tskid. This is similar to tk_set_reg.
Registers cannot be set for the task currently in RUN state. Except when a task-independent portion is executing, the current RUN state task is the invoking task.
When NULL is designated for pk_regs, pk_eit, or pk_cregs, the corresponding register is not set.
The contents of T_REGS, T_EIT, and T_CREGS are implementation-dependent.
