HI,
i am trying to multiply 2 2D arrays (a,b) using fork.
The answer will be at c.
Each child have to calculate 1 row of c.
The code is right, as i think of it, with no errors but i dont get the correct c array...
I think there is maybe a mistake in i dimension ...
Anyway, here is the code:

SYNOPSIS

#include <mlib.h>
mlib_status mlib_SignalConv_S16_S16_Sat(mlib_s16 *dst, const mlib_s16 *src1, const mlib_s16 *src2, mlib_s32 m, mlib_s32 n);

DESCRIPTION
Each of these functions performs convolution.
For monaural signals, the following equation is used:
m-1
dst[i] = SUM (src1[j] * src2[i - j]) if m <= n
j=0
n-1
dst[i] = SUM (src2[j] * src1[i - j]) if m > n
j=0
where i = 0, 1, ..., (m + n - 2).
For stereo signals, the following equation is used:
m-1
dst[2*i] = SUM (src1[2*j] * src2[2*(i - j)])
j=0
m-1
dst[2*i + 1] = SUM (src1[2*j + 1] * src2[2*(i - j) + 1])
j=0
if m <= n, or
n-1
dst[2*i] = SUM (src2[2*j] * src1[2*(i - j)])
j=0
n-1
dst[2*i + 1] = SUM (src2[2*j + 1] * src1[2*(i - j) + 1])
j=0
if m > n; where i = 0, 1, ..., (m + n - 2).
PARAMETERS
Each of the functions takes the following arguments:
dst Destination signal array.
src1 First source signal array.
src2 Second source signal array.
m Number of samples in the first source signal array.
n Number of samples in the second source signal arrays.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
