If \fBesballoc\fR(9F) is unable to allocate a message and data block header to go with its externally supplied data buffer, \fBesbbcall()\fR can be used to schedule the routine \fIfunc\fR, to be called with the argument \fIarg\fR when a buffer becomes available. The \fIfunc\fR argument can be a routine that calls \fBesballoc\fR(9F) or it may be another kernel function. .SH RETURN VALUES .sp .LP On success, a \fBbufcall\fR \fBID\fRis returned. On failure, \fB0\fR is returned. The value returned from a successful call should be saved for possible future use with \fBunbufcall()\fR should it become necessary to cancel the \fBesbbcall()\fR request (as at driver close time). .SH CONTEXT .sp .LP The \fBesbbcall()\fR function can be called from user, interrupt, or kernel context. .SH SEE ALSO .sp .LP \fBallocb\fR(9F), \fBbufcall\fR(9F), \fBesballoc\fR(9F), \fBtimeout\fR(9F), \fBunbufcall\fR(9F), \fBdatab\fR(9S) .sp .LP \fIWriting Device Drivers in Oracle Solaris 11.4\fR \fISTREAMS Programming Guide\fR
