Function vfs_read

pub unsafe extern "C" fn vfs_read(
    fd: c_int,
    dest: *mut c_void,
    count: size_t,
) -> ssize_t

@brief Read bytes from an open file

@param[in] fd fd number obtained from vfs_open @param[out] dest destination buffer to hold the file contents @param[in] count maximum number of bytes to read
