the index of libc shows:
* pclose: Pipe to a Subprocess.
* perror: Error Messages.
* pipe: Creating a Pipe.
* popen: Pipe to a Subprocess.
* pow: Exponents and Logarithms.
* printf: Formatted Output Functions.
* psignal: Signal Messages.
* putc: Simple Output.
* putchar: Simple Output.
no function pow10 and therefore the linker comlains.
maybe its the funktion pow, you might want.
- Function: double pow (double BASE, double POWER)
This is a general exponentiation function, returning BASE raised
to POWER.
hope that helps,
Helmut
