248 | * limitations: | |
249 | * | |
250 | * * The `*` width specifier is not accepted. | |
251 | * * The `*` precision specifier is not accepted. | |
252 | * * The `j` and `t` length modifiers are not accepted. | |
253 | * * The `n` format specifier is not accepted. | |
254 | * * The format specifiers defined in <inttypes.h> are not accepted | |
255 | * except for `PRId64`, `PRIu64`, `PRIx64`, `PRIX64`, `PRIo64`, and | |
256 | * `PRIi64`. | |
257 | * | |
258 | * `intro` specifies which special character immediately following an | |
259 | * introductory `%` character in `fmt` is used to indicate a custom | |
260 | * conversion specifier. For example, if `intro` is '@', then any `%@` | |
261 | * sequence in `fmt` is the beginning of a custom conversion specifier. | |
262 | * | |
263 | * When a custom conversion specifier is encountered in `fmt`, | |
264 | * the function calls `handle_specifier`. This callback receives: | |
265 | * | |
266 | * `priv_data`: | |
267 | * Custom, private data. | |
268 | * | |
269 | * `buf`: | |
270 | * Address of the current buffer pointer. `*buf` is the position to | |
271 | * append new data. The callback must update `*buf` when appending | |
272 | * new data. The callback must ensure not to write passed the whole | |
273 | * buffer passed to bt_common_custom_vsnprintf(). | |
274 | * | |
275 | * `avail_size`: | |
276 | * Number of bytes left in whole buffer from the `*buf` point. | |
277 | * | |
278 | * `fmt`: | |
279 | * Address of the current format string pointer. `*fmt` points to | |
280 | * the introductory `%` character, which is followed by the | |
281 | * character `intro`. The callback must update `*fmt` so that it | |
282 | * points after the whole custom conversion specifier. | |
283 | * | |
284 | * `args`: | |
285 | * Variable argument list. Use va_arg() to get new arguments from | |
286 | * this list and update it at the same time. | |
287 | * | |
