pSOS+ System Calls q_asend
q_asend (pSOS+m kernel only) Asynchronously posts a message to an ordinary
message queue.
#include
unsigned long q_asend(
unsigned long qid, /* queue identifier */
unsigned long msg_buf[4] /* message buffer */
)
Description
Arguments
Return Value
Error Codes
This system call functions the same as q_send() except that it executes
asynchronously. Refer to the description of q_send() for further information. For a
detailed description of asynchronous services, refer to the pSOSystem Systems
Concepts manual.
qid Specifies the queue ID of the target queue.
msg_buf Specifies the message to send.
When called in a system running the pSOS+m kernel this call always returns 0. The
pSOS+ kernel (the single processor version) returns ERR_SSFN.
Should the call fail, if present, the node's MC_ASYNCERR routine is invoked and the
following error codes may be reported:
Hex Mnemonic Description
0x05 ERR_OBJDEL Queue has been deleted.
0x06 ERR_OBJID qid incorrect; failed validity check.
0x07 ERR_OBJTYPE Object type doesn’t match object ID;
failed validity check.
0x34 ERR_NOMGB Out of system message buffers.
