Okay, here's the complete relevant snippet:
char str[100]; // Temporary string to hold data to be
displayed.
// Determine the length of text that will fit within the
bounds.
textLen = StrLen(pdb->strName);
if (FntCharsWidth(pdb->strName,textLen) < width)
// If the string was short enough to fit wholly in the
cell...
{
StrCopy(str,pdb->strName);
}
else
// The string was too long to fit within the cell...
{
width -= FntCharsWidth("...",3); // New width takes
into account addition of elipsis.
textLen = StrLen(pdb->strName); // Reset in case it
was tweaked.
FntCharsInWidth(pdb->strName, &width, &textLen,
&fits);
// Copy as many characters as will fit.
StrNCopy(str,pdb->strName,textLen);
// Append the elipsis ("...").
CharPtr pChar = str + textLen; /*
Questionable code line 1 */
for (int loop = 0; loop < 3; loop++) /*
Questionable code line 2 */
*(pChar++) = '.'; /*
Questionable code line 3 */
*pChar = '\0'; /*
Questionable code line 4 */
// StrCat(str,"...");
textLen = StrLen(str);
}
If I cut out all the 'Questionable code' lines and uncomment the StrCat()
call, it stops functioning correctly. I'll get strange artifacts like a
colon, THEN the three periods following my string rather than just the three
periods! These artifacts (though randomly distributed among my strings)
consistently appear and disappear each time I switch between the two
methods.
If I'm calling something incorrectly, I don't see it.
