converting qstring to unsigned char

[havij000]

Hello every body,

I am new to Qt and need to convert a qstring variable which is a Hex number to an unsinged char array type as you can see bellow

QString str = "1234"; // which is the 0x1234 number

QString str = "1234"; // which is the 0x1234 number

To copy to clipboard, switch view to plain text mode 

and I need to store it in one of the below data structure fields which is 2 byte (for instance the "unsigned char Base_Addrs[2]" field) :

struct wrt_rqst_
{
        unsigned char Dest_MAC[6];
        unsigned char Src_MAC[6];
        unsigned char Eth_Length[2];//should be 0x0800
        unsigned char Wrt_Cmd[2];//should be 0x0000
        unsigned char Base_Addrs[2];
        unsigned char Data_Length[2];//should be 0x02EB
        unsigned char data[1494];//should be set all az 0
 
}*wrt_buff;

struct wrt_rqst_
{
        unsigned char Dest_MAC[6];
        unsigned char Src_MAC[6];
        unsigned char Eth_Length[2];//should be 0x0800
        unsigned char Wrt_Cmd[2];//should be 0x0000
        unsigned char Base_Addrs[2];
        unsigned char Data_Length[2];//should be 0x02EB
        unsigned char data[1494];//should be set all az 0

}*wrt_buff;

how should I convert the qstring to unsigned char?

Thanks.

int val = str.toInt(0, 16);

int val = str.toInt(0, 16);
