Name

mlib_SignalMulS_F32, mlib_SignalMulS_F32S - multiplication by a scalar

Synopsis

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

mlib_status mlib_SignalMulS_F32(mlib_f32 *srcdst, const mlib_f32 *c,
     mlib_s32 n);
mlib_status mlib_SignalMulS_F32S(mlib_f32 *srcdst, const mlib_f32 *c,
     mlib_s32 n);

Description

Each of these functions performs multiplication by a scalar.

Parameters

Each of the functions takes the following arguments:

srcdst

Input and output signal array.

c

Scaling factor. In the stereo version, c[0] contains the scaling factor for channel 0, and c[1] holds the scaling factor for channel 1.

n

Number of samples in the input signal arrays.

Return Values

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