[alsa-devel] [PATCH] pcm: use the same set of uint_XX types everywhere

John Spencer maillist-alsa at barfooze.de
Wed Oct 2 17:36:49 CEST 2013


previously, pcm.h prototyped the functions
snd_pcm_format_silence* with u_int_XX types
(legacy BSD types from sys/types.h),
while the implementation in pcm_misc.c used the C99
stdint.h types uint_XX.

this caused compilation errors on systems where the
typedef for u_int_XX and uint_XX is not exactly the same.

we fix it by using the C99 stdint.h types everywhere.
