Some users report that they log out automatically after logon. After tracking and observation, they found that these users are all dynamic IP addresses, and the session in ecmall happens to be related to IP addresses. Therefore, they cannot find the user and fail to return to session 2, you need to log on again.
How can this problem be solved?

can also print the data in hexadecimal format:
Sprintf (s, "% 8x", 4567); // lowercase hexadecimal notation, with 8 width positions and right alignment
Sprintf (s, "%-8X", 4568); // in hexadecimal notation, the width occupies 8 positions and is left aligned.
In this way, the hexadecimal string of an integer is easy to obtain, but when printing the hexadecimal content, we usually want an equal-width format with 0 on the left, what should we do? Simply add 0 to the number that represents
; iprintf("%02x ", c[i]);}printf("\r\n------------\r\n");for(i=0; iprintf("%d", a[i]);}return 0;}

General
RdebugIs a useful utility for checking a log of specific messages generated by the Running code. This feature is helpful when the breakpoint/step debug tricks 'using space has been limited.
To useRdebug, Include the header file,E32debug. h. (In 2nd Edition SDK, rdebug class declared inE32svr. h)
#include
Then, add the following to any place in your code:
// code before logRDebug::Print(_L("### Log%d%08x"), 5, 0xABCDEF12);// code after log
