Are your strings null terminated? That is, are you sure they have an '\0'
at the end of them? strcat, I think, looks for the null and then expands
from there. I'm not sure what it does when it cannot find one. Also, you
might want to consider strncat, I think that's a little "safer".

Subject: [Tinyos-help] The string becomes unrecoginizable after some
stringoperation
Sent: Thursday, November 22, 2007 12:30 AM
Dear all,
I found that the string under nesc, once being processed by some string
functions, for example, strcat() and strcpy(), will become totoally
disordered and unrecognizable.
for example:
aFunction(*OriginalData)
{
char DataToSend[50];
strcpy(DataToSend,OriginalData);
strcat(DataToSend,"}"};
//here if I print DataToSend out, it is totally disordered, but
DataToSend if fine.
...
}
I am wondering if there is any restrictions on string processing? Or this
does not happen to any of you?
Thank you.
Enric
