Sometimes, with larger projects, you will want to compile a function separately. You can use the -c flag to do this.
----

Basically i do some plug-in in ksh. what you said is correct, i am using ksh-88 only.

In my project, I need to write some tools(functions) in C and compile a function separately, and then call that funtion's executables in ksh script.

I have included -c flag in cc. but it is generating object files only

like

$ cc -c seq.c
$
$
$ cat seq.c

#include <stdio.h>
seq(num)
int num;
{
int i,sum;
for (i=1; i<=num;i++)
sum+=i;
return(sum);
}
$ ll seq*
-rw-rw-r-- 1 ict ict 99 Jan 23 17:16 seq.c
-rw-rw-r-- 1 ict ict 576 Jan 28 09:47 seq.o

Can you please help out in this problem. how can i make executables using this. I hope, this might be very simple thing for you.

Thanks lot.

NAME
frexp, frexpf, frexpl - extract mantissa and exponent from a floating-point number SYNOPSIS
cc [ flag... ] file... -lm [ library... ] #include <math.h> double frexp(double num, int *exp); float frexpf(float num, int *exp); long double frexpl(long double num, int *exp); DESCRIPTION
These functions break a floating-point number into a normalized fraction and an integral power of 2. They store the integer exponent in the int object pointed to by exp. RETURN VALUES
For finite arguments, these functions return the value x, such that x is a double with magnitude in the interval [1/2, 1) or 0, and num equals x times 2 raised to the power *exp. If num is NaN, NaN is returned and the value of *exp is unspecified. If num is +- 0, +- 0 is returned and the value of *exp is 0. If num is +-Inf, num is returned and the value of *exp is unspecified. ATTRIBUTES
