84 | * the version here does not include floating point... | ||
85 | * | ||
86 | * snprintf() is used instead of sprintf() as it does limit checks | ||
87 | * for string length. This covers a nasty loophole. | ||
88 | * | ||
89 | * The other functions are there to prevent NULL pointers from | ||
90 | * causing nast effects. | ||
