'read' function in uClibc 0.9.32

What is the first function run in uClibc when user application call read(...)?

I only could find the following related code under uClibc-0.9.32\libc\sysdeps\linux\common\read.c.

Code:

_syscall3(ssize_t, read, int, fd, __ptr_t, buf, size_t, count)

#ifndef __LINUXTHREADS_OLD__

libc_hidden_def(read)

#else

libc_hidden_weak(read)

strong_alias(read,__libc_read)

#endif

Thank you.

You can try fread function in fread.c under /libc/stdio. Digging into the function, you should find read function.
