Good stuff, AkshayHedge!
One suggestion for the function implementation. If you variables local to the function, declare them as formal in the function declaration. Otherwise their scope is global and they may clash with other globals and the result may be something that's not desirable.
The function call will stay the same - you're passing only what you need to pass.
Here's the illustration of your function:
Code:
function find(Arr,key,arg,   low,upp,i){
                              low = upp = ""

                              for(i in Arr){
                                            if(i<key)
                                                 {
                                                   low =  (low && low > i) ? low : i
                                                 }
                                            if(i>key)
                                                 {
                                                   upp =  (upp && upp < i) ? upp : i
                                                 }
                                             }

                         low  =  (low != "") ? low : "-"
                         upp  =  (upp != "") ? upp : "-"

                        if(arg=="up"){return upp}
                   else if(arg=="dw"){return low}
}

       mlib_status mlib_SignalLimit_F32S(mlib_f32 *srcdst, const mlib_f32 *low, const mlib_f32 *high, mlib_s32 n);

DESCRIPTION

       Each of these functions performs hard limiting.

       For monaural signals, the following equation is used:

       dst[i] = low[0]		 if src[i] < low[0]
       dst[i] = src[i]		 if low[0] <= src[i] < high[0]
       dst[i] = high[0] 	 if src[i] >= high[0]

       where i = 0, 1, ..., (n - 1).

       For stereo signals, the following equation is used:

       dst[2*i] = low[0]	 if src[2*i] < low[0]
       dst[2*i] = src[2*i]	 if low[0] <= src[2*i] < high[0]
       dst[2*i] = high[0]	 if src[2*i] >= high[0]

       dst[2*i+1] = low[1]	 if src[2*i+1] < low[1]
       dst[2*i+1] = src[2*i+1]	 if low[1] <= src[2*i+1] < high[1]
       dst[2*i+1] = high[1]	 if src[2*i+1] >= high[1]

       where i = 0, 1, ..., (n - 1).

PARAMETERS

       Each of the functions takes some of the following arguments:

       dst	       Destination signal array.

       src	       Source signal array.

       srcdst	       Source and destination signal array.

       low	       Lower input limit.  In the stereo version, low[0] contains the lower limit for channel 0, and  low[1]  contains	the  lower
		       limit for channel 1.

       high	       Upper  input  limit.  In the stereo version. high[0] contains the upper limit for channel 0, and high[1] contains the upper
		       limit for channel 1.

       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.
