Writes the specified buffer data without waiting for I/O to complete.
#include <sys/types.h> #include <sys/errno.h> #include <sys/buf.h> int bawrite ( bp) struct buf *bp;
| Item | Description |
|---|---|
| bp | Specifies
the address of the buffer structure. On a platform that supports storage keys, the passed in bp parameter must be in the KKEY_PUBLIC or KKEY_BLOCK_DEV protection domain. |
The bawrite kernel service sets the asynchronous flag in the specified buffer and calls the bwrite kernel service to write the buffer.
For a description of how the three buffer-cache write subroutines work, see "Block I/O Buffer Cache Services: Overview" in AIX® Version 7.1 Kernel Extensions and Device Support Programming Concepts.
The bawrite kernel service can be called from the process environment only.
