Use this system macro to request special system inter-processor
communication function services.
Format
- RTYPE
- This required parameter specifies the type of request you are
making. The only valid request is:
- FLUSHQ
- This service will send all SIPC items that have been queued for a specific
processor.
- REG=Rx
- This parameter specifies a register containing the address of the entry
for the specific processor in the IPC global table (IGT). Specify a
general register in the range R0 through R7. The IGT is defined by the
DCTIGT DSECT.
Entry Requirements
R14 and R15 must be available for use by this macro.
Return Conditions
- Control is returned to the next sequential instruction (NSI).
- The contents of R0 through R13 are preserved across this macro
call.
Programming Considerations
- This macro can only be run on the main I-stream only.
- The SICFC macro has an interface that is not guaranteed across releases of
the TPF system. Unauthorized use of this macro may expose you to
interface and/or processing errors.
- This macro is intended to be used by system IPC support programs
only.
