Subject: [PATCH] linux_sysfs: Use pwrite/pread instead of 64bit versions
|
|
|
|
pread64/pwrite64 are aliased to pread/pwrite when largefile support is
|
|
enabled e.g. using _FILE_OFFSET_BITS=64 macro
|
|
|
|
This helps it compile on latest musl C library based systems where these
|
|
functions are put under _LARGEFILE64_SOURCE which is to be removed once
|
|
all packages start using 64bit off_t, it works with glibc becuase
|
|
_GNU_SOURCE feature macro also defines _LARGEFILE64_SOURCE, thats not
|
|
the case with musl
