4 | Subject: [PATCH] v4l2: Define ioctl_req_t for posix/linux case | ||
5 | |||
6 | this is an issue seen with musl based linux distros e.g. alpine [1] | ||
7 | musl is not going to change this since it breaks ABI/API interfaces | ||
8 | Newer compilers are stringent ( e.g. clang16 ) which can now detect | ||
9 | signature mismatches in function pointers too, existing code warned but | ||
10 | did not error with older clang | ||
11 | |||
12 | Fixes | ||
13 | gstv4l2object.c:544:23: error: incompatible function pointer types assigning to 'gint (*)(gint, ioctl_req_t, ...)' (aka 'int (*)(int, unsigned long, ...)') from 'int (int, int, ...)' [-Wincompatible-function-pointer-types] | ||
14 | v4l2object->ioctl = ioctl; | ||
