323 | * limitations: | |
324 | * | |
325 | * * The `*` width specifier is not accepted. | |
326 | * * The `*` precision specifier is not accepted. | |
327 | * * The `j` and `t` length modifiers are not accepted. | |
328 | * * The `n` format specifier is not accepted. | |

330 | * except for `PRId64`, `PRIu64`, `PRIx64`, `PRIX64`, `PRIo64`, and | |
331 | * `PRIi64`. | |
332 | * | |
333 | * `intro` specifies which special character immediately following an | |
334 | * introductory `%` character in `fmt` is used to indicate a custom | |
335 | * conversion specifier. For example, if `intro` is '@', then any `%@` | |
336 | * sequence in `fmt` is the beginning of a custom conversion specifier. | |
337 | * | |
338 | * When a custom conversion specifier is encountered in `fmt`, | |
339 | * the function calls `handle_specifier`. This callback receives: | |
340 | * | |
341 | * `priv_data`: | |
342 | * Custom, private data. | |
343 | * | |
344 | * `buf`: | |
345 | * Address of the current buffer pointer. `*buf` is the position to | |
346 | * append new data. The callback must update `*buf` when appending | |
347 | * new data. The callback must ensure not to write passed the whole | |
348 | * buffer passed to bt_common_custom_vsnprintf(). | |
349 | * | |
350 | * `avail_size`: | |
351 | * Number of bytes left in whole buffer from the `*buf` point. | |
352 | * | |
353 | * `fmt`: | |
354 | * Address of the current format string pointer. `*fmt` points to | |
355 | * the introductory `%` character, which is followed by the | |
356 | * character `intro`. The callback must update `*fmt` so that it | |
357 | * points after the whole custom conversion specifier. | |
358 | * | |
359 | * `args`: | |
360 | * Variable argument list. Use va_arg() to get new arguments from | |
361 | * this list and update it at the same time. | |
362 | * | |
