The \fIname\fR argument is the specific +controller instance (for example, "sci0" or "loopback"). This controller handle +is used for subsequent RSMAPI calls. +.sp +.LP +The \fBrsm_get_controller_attr()\fR function obtains a controller's attributes +through the \fIattr\fR argument. The \fIchdl\fR argument is the controller +handle obtained by the \fBrsm_get_controller()\fR call. The attribute +structure is defined in the <\fBrsmapi\fR> header. +.sp +.LP +The \fBrsm_release_controller()\fR function releases the resources associated +with the controller identified by the controller handle \fIchdl\fR, obtained by +calling \fBrsm_get_controller()\fR. Each \fBrsm_release_controller()\fR call +must have a corresponding \fBrsm_get_controller()\fR call. It is illegal to +access a controller or segments exported or imported using a released +controller. +.SH RETURN VALUES +.sp +.LP +Upon successful completion, these functions return 0. Otherwise, an error value +is returned to indicate the error. +.SH ERRORS +.sp +.LP +The \fBrsm_get_controller()\fR, \fBrsm_get_controller_attr()\fR, and +\fBrsm_release_controller()\fR functions can return the following errors: +.sp +.ne 2 +.mk +.na +\fB\fBRSMERR_BAD_CTLR_HNDL\fR \fR +.ad +.RS 25n +.rt +Invalid controller handle. +.RE + +.sp +.LP +The \fBrsm_get_controller()\fR and \fBrsm_get_controller_attr()\fR functions +can return the following errors: +.sp +.ne 2 +.mk +.na +\fB\fBRSMERR_BAD_ADDR\fR \fR +.ad +.RS 20n +.rt +Bad address. +.RE + +.sp +.LP +The \fBrsm_get_controller()\fR function can return the following errors: +.sp +.ne 2 +.mk +.na +\fB\fBRSMERR_CTLR_NOT_PRESENT\fR \fR +.ad +.sp .6 +.RS 4n +Controller not present. +.RE + +.sp +.ne 2 +.mk +.na +\fB\fBRSMERR_INSUFFICIENT_MEM\fR \fR +.ad +.sp .6 +.RS 4n +Insufficient memory. +.RE + +.sp +.ne 2 +.mk +.na +\fB\fBRSMERR_BAD_LIBRARY_VERSION\fR \fR +.ad +.sp .6 +.RS 4n +Invalid library version. +.RE + +.SH ATTRIBUTES +.sp +.LP +See \fBattributes\fR(5) for descriptions of the following attributes: +.sp + +.sp +.TS +tab() box; +lw(2.75i) |lw(2.75i) +lw(2.75i) |lw(2.75i) +. +\fBATTRIBUTE TYPE \fR\fBATTRIBUTE VALUE\fR +_ +Interface StabilityEvolving +_ +MT-LevelMT-Safe +.TE + +.SH SEE ALSO +.sp +.LP +\fBrsm_memseg_export_create\fR(3RSM), \fBrsm_memseg_import_connect\fR(3RSM), +\fBattributes\fR(5) |
