bash: read file line by line (lines have '\0') - not full line has read???
I am using the while-loop to read a file.
The file has lines with null-terminated strings (words, actually.)
What I have by that reading - just a first word up to '\0'!
I need to have whole string up to 'new line' - (LF, 10#10, 16#A)

What I am doing wrong?
Code:
   #make file 'grb' with '\0's :
--0223-112518:~/develop/src> printf \
> "hello\0 word\0 done\0\n"\
> "this\0 next\0 line\0\n"\
> "last\0 ln\n"\
> >grb
--0223-112602:~/develop/src>
  # now reading it line by line:
--0223-112603:~/develop/src> while IFS= read ln; do echo "$ln"; done < grb
hello
this
last
  # - only first words are printed ?!?!
--0223-112714:~/develop/src> cat grb
hello word done
this next line
last ln
--0223-112738:~/develop/src>

How to get whole line inside of the loop?

Thanks!

mlib_SignalEmphasize_S16_S16_Sat(3MLIB) 		    mediaLib Library Functions			   mlib_SignalEmphasize_S16_S16_Sat(3MLIB)

NAME

       mlib_SignalEmphasize_S16_S16_Sat, mlib_SignalEmphasize_S16S_S16S_Sat, mlib_SignalEmphasize_F32_F32, mlib_SignalEmphasize_F32S_F32S - signal
       pre-emphasizing

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_SignalEmphasize_S16_S16_Sat(mlib_s16 *dst, const mlib_s16 *src, void *filter, mlib_s32 n);

       mlib_status mlib_SignalEmphasize_S16S_S16S_Sat(mlib_s16 *dst, const mlib_s16 *src, void *filter, mlib_s32 n);

       mlib_status mlib_SignalEmphasize_F32_F32(mlib_f32 *dst, const mlib_f32 *src, void *filter, mlib_s32 n);

       mlib_status mlib_SignalEmphasize_F32S_F32S(mlib_f32 *dst, const mlib_f32 *src, void *filter, mlib_s32 n);

DESCRIPTION

       Each of these functions applies the preemphasizer to one signal packet and updates the filter states.

       For monaural signals, the following equation is used:

       dst[i] = src[i] - alpha*src[i - 1]

       where i = 0, 1, ..., (n - 1); src[-1] = 0.

       For stereo signals, the following equation is used:

       dst[2*i]     = src[2*i]	   - alpha*src[2*(i - 1)]
       dst[2*i + 1] = src[2*i + 1] - alpha*src[2*(i - 1) + 1]

       where i = 0, 1, ..., (n - 1); src[-2] = src[-1] = 0.

PARAMETERS

       Each of the functions takes the following arguments:

       dst	       Destination signal array.

       src	       Source signal array.

       filter	       Internal filter structure.

       n	       Number of samples in the source signal array.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
