As far as wsprintf is concerned, your format string TEXT("%s\0%s") is the
same as "%s" because a string ends at the first NUL.

This is better, but when you append the next thing, it's not going to follow
the NUL, it's going to replace the NUL, because the string ends at the first
NUL.

ASCII-Z strings aren't counted, so they cannot contain embedded nulls.

try:
TCHAR* szBuffer = (TCHAR*)malloc(BIGSIZE);
TCHAR* pchEnd = szBuffer;

for( ... ) {
/* from wsprintf documentation:
If the function succeeds, the return value is the number of
characters stored in the output buffer, not counting the terminating null
character.
Add one for the terminating null character.
*/
pchEnd += 1 + wsprintf(pchEnd, .....);
}
*(pchEnd++) = '\0'; /* doubling the last null */
int size = pchEnd - szBuffer;


Or, you can have a unique separator (like '#' if that never appears in the
filename) and then use strtok to replace all the '#' by NULs.
