Overview

How can I find out the software build version of a S60 device in numeric format?

Description

The method SysUtil::GetSWVersion(TDes& aValue) returns the device software version information as a string. The same information is returned in a dialog when the sequence *#0000# is entered in phone idle view. Sometimes it is useful for an application to know the version information as integer values. The following code demonstrates how to extract the software version as unsigned integer values from the string:
#include <SysUtil.h>    // link against sysutil.lib
void GetNumericSWVersionL(TUint& aMajor, TUint& aMinor, TUint& aBuild)
    {
    TBuf<KSysUtilVersionTextLength> versionString;
    User::LeaveIfError(SysUtil::GetSWVersion(versionString));
    TLex parser(versionString);
    // Skip non-digit characters from the beginning
    while(!parser.Peek().IsDigit())
        parser.Get();
    // Get major version value
    User::LeaveIfError(parser.Val(aMajor));
    // Next character should be '.'
    if(parser.Get() != '.')
        User::Leave(KErrBadDescriptor);
    // Get minor version value
    User::LeaveIfError(parser.Val(aMinor));
    // If next char is '.' or '(', string contains
    // also the build version
    TChar next = parser.Get();
    if(next == '.' | next == '(')
        User::LeaveIfError(parser.Val(aBuild));
    else
        aBuild = 0;
    }
