pt_getbuf pSOS+ <strong>System</strong> <strong>Calls</strong><br />

Notes<br />

See Also<br />

1. Buffers always start on long word boundaries.<br />

2. It is not possible to wait for a buffer. pt_getbuf() unconditionally returns.<br />

Multiprocessor Considerations<br />

If the input ptid identifies a global partition residing on another processor node,<br />

then the pSOS+ kernel internally makes an RSC to that remote node to allocate the<br />

buffer.<br />

Callable From<br />

■ Task.<br />

■ ISR, if the partition is local to the node from which pt_getbuf() is made.<br />

■ KI, if the partition is local to the node from which pt_getbuf() is made.<br />

■ Callout, if the partition is local to the node from which pt_getbuf() is made.<br />
