Update wrapFunction example

1. Search for the function with the requested name instead of the empty name.
2. Save updated file.

A sample input I used to test this example:

#include <stdio.h>

int a[256];

void *origMalloc(unsigned long size)
{
    printf("origMalloc\n");
    return &a[size];
}

void *fastMalloc(unsigned long size)
{
    printf("fastMalloc\n");
    return &a[size];
}

int main(void)
{
    int x;
    scanf("%d", &x);
    scanf("%d", (int *)origMalloc(x));
    printf("%d\n", *(int *)origMalloc(x));
    return 0;
}

Thanks for the careful checks.
