kdk_hw_free_hw - 释放kdk_hw_get_hwinfo返回的硬件信息结构体
|
|
.SH SYNOPSIS
|
|
.nf
|
|
.B #include <libkyhw.h>
|
|
.sp
|
|
.BI "extern void kdk_hw_free_hw(struct HWInfo *"list ");"

.sp
|
|
Link with \fI\-lkyhwinfo\fP.
|
|
.SH "Detailed Description"
|
|
The main function of the interface is to release the hardware information structure returned by the
|
|
.I kdk_hw_get_hwinfo.
|
|
.PP
|
|
The argument
|
|
.I list
|
|
is the return value of the
|
|
.I kdk_hw_get_hwinfo.
|
|
.SH "RETURN VALUE"
|
|
No return value
