Thanks for the help, but i was more searching this soultion

print.h

Code:

#ifndef PRINT_H_INCLUDED
#define PRINT_H_INCLUDED

#include <stdio.h>
#include <stdint.h>
#include <stdlib.h>
#include "header.h"
#include "error.h"

#define PrintArray(array, sizeArray, typeData) _PrintArray(array, sizeArray, typeData, __FILE__, __FUNCTION__, __LINE__)

void _PrintArray(void *array, int64_t sizeArray, uint8_t typeData, char const *fileName, char const *functionName, const int64_t lineNumber);
#endif // PRINT_H_INCLUDED

So this define does all the work

Code:

#define PrintArray(array, sizeArray, typeData) _PrintArray(array, sizeArray, typeData, __FILE__, __FUNCTION__, __LINE__)

In main.c i can still call the PrintArray() without given the file, function and line parameters, so when an event of handling error occuors due to the parameters in main.c the error function will return the file, func and line of the main.c where the errors has happened. The programmer who use this function will have a littel handling error rutine inside without notice it.

Example


changed INT8 definition to a number out of range like 50 for example

main.c

Code:

#include "print.h"
#include "array.h"
#include "allocator.h"
#include "sort.h"
#include "aritmethic.h"

int main()
{
    int8_t numeros[] = {23,45,78,23};
    PrintArray(numeros,NumberOfArrayElements(numeros),50);
    return EXIT_SUCCESS;
}

output
