Include regex.h from para.h.2025-05-19T17:35:58ZAndre Nollmaan@tuebingen.mpg.de2025-05-18T20:05:45Zurn:sha1:67388cd4fae0cfd1674aada937f4f4d2faeeee1f
Every .c file includes it anyway.
New audio formats: 32 bit float (little and big endian).2024-09-15T16:26:44ZAndre Nollmaan@tuebingen.mpg.de2018-09-08T10:11:33Zurn:sha1:70c8a6a47190c1e92b61f2f1a1ecf7aa5093b9c8
At least the little endian version seems to be popular these days. It
is only supported by ALSA, however. To check whether a given wave
file employs one of the two SF_FLOAT formats (aka IEEE float) we have
to consult the format code, a 16 bit integer stored at offset 20 of
the wave header which describes the waveform data according to the
table below.
0x0001 PCM
0x0003 IEEE float
0x0006 8-bit ITU-T G.711 A-law
0x0007 8-bit ITU-T G.711 MU-law
0xFFFE Determined by SubFormat
Additional checks are added to check_wav_post_select() which make
sure that the format code is either 1 or 3, and that the number is
compatible with the bits per sample value.
Consolidate EOF error codes.2023-03-11T18:16:46ZAndre Nollmaan@tuebingen.mpg.de2022-12-30T14:08:59Zurn:sha1:b087c1356e3eebf656aa1c783ff7e50c9de5a229
Currently we have ~15 error codes which indicate an EOF condition. One
should suffice, so drop all codes except the generic E_EOF and use
that everywhere.
Merge topic branch t/overflow into master2022-10-03T16:01:20ZAndre Nollmaan@tuebingen.mpg.de2022-10-03T15:59:56Zurn:sha1:563b56a493d6a2bdcdebafadd907954dbe1de8a8
This series implements a new memory allocation API which checks
for overflows. The first part of the series just renames the main
allocation functions. Later patches in the series implement allocators
which take two size_t arguments (like calloc(3)) and check whether the
multiplication overflows by employing the __builtin_mul_overflow()
primitive supported by gcc and clang. This requires us to bump the
lowest supported gcc and clang version.
* refs/heads/t/overflow:
build: Compile with -ftrapv.
string: Introduce arr_zalloc().
string: Introduce arr_alloc().
string: Introduce arr_realloc() and check for integer overflow.
string: Rename para_calloc() -> zalloc().
string: Rename para_malloc() -> alloc().
string: Overhaul para_strdup().
Rename ->{pre,post}_select methods to ->{pre,post}_monitor.2022-08-25T13:37:26ZAndre Nollmaan@tuebingen.mpg.de2021-10-10T16:10:09Zurn:sha1:e3a7e12639c34fd86d48a072beb48add8c498d09
The word "monitor" is neutral and continues to be correct after the
switch from select(2) to poll(2).
Pure rename, nothing to see here.
Misc documentation cleanups related to select().2022-08-25T13:37:26ZAndre Nollmaan@tuebingen.mpg.de2021-10-07T20:16:09Zurn:sha1:742c8b3f79a59278ced71e1855da1846b157b494
Assorted comment cleanups which avoid to talk about select(2) and
fd sets. No code changes.
Hide implementation of para_fd_set().2022-08-25T13:37:26ZAndre Nollmaan@tuebingen.mpg.de2021-10-03T19:52:02Zurn:sha1:bb899fb1a0c279a2890ff30d11bf7aec50fb92ed
This preparatory patch for replacing select() renames para_fd_set()
to sched_fd_set(), moves it to sched.c and makes it static. All
users are modified to call either of the two new public functions
sched_monitor_{read,write}fd() which take a pointer to struct sched
rather than an fd set pointer.
sched: Introduce sched_{read,write}_ok().2022-08-25T13:37:26ZAndre Nollmaan@tuebingen.mpg.de2021-09-30T20:35:10Zurn:sha1:181beb316afad036ac01a778544c5dec0a8d51c7
Two trivial wrappers for FD_ISSET() which hide the fact that we're
still using the select(2) API.
