3417 | |
3418 | The first function writes to sys.stdout; the second to sys.stderr. When |
3419 | there is a problem, they write to the real (C level) stdout or stderr; |
3420 | no exceptions are raised. |
3421 | |
3422 | PyErr_CheckSignals() is not called to avoid the execution of the Python |
3423 | signal handlers: they may raise a new exception whereas sys_write() |
3424 | ignores all exceptions. |
3425 | |
3426 | Both take a printf-style format string as their first argument followed |
3427 | by a variable length argument list determined by the format string. |
3428 | |
3429 | *** WARNING *** |
3430 | |
3431 | The format should limit the total size of the formatted output string to |
3432 | 1000 bytes. In particular, this means that no unrestricted "%s" formats |
3433 | should occur; these should be limited using "%.<N>s where <N> is a |
3434 | decimal number calculated so that <N> plus the maximum size of other |
3435 | formatted text does not exceed 1000 bytes. Also watch out for "%f", |
3436 | which can print hundreds of digits for very large numbers. |
