Summary
The REPLY[X|XL] procedures are used to send a reply message to a message received earlier in
a corresponding call to READUPDATE[X|XL] on the $RECEIVE file.
The REPLY[X|XL] procedures can be called even if there are incomplete nowait I/O operations
pending on $RECEIVE.
NOTE: The REPLYXL procedure is supported on systems running H06.18 and later H-series RVUs
and J06.07 and later J-series RVUs.
REPLY[X|XL] performs the same operation as the FILE_REPLY64_ Procedure (page 499), which is
recommended for new code.
Key differences in FILE_REPLY64_ are:
• The pointer parameters are 64 bits wide.
• The write-count parameter is 32 bits wide.
• The procedure returns an error code value rather than a condition code, simplifying
error-handling code.
