Dear respected programmers. Please could you help me (again) on how to put the following code into functions for my program.
I have read on-line and understand how functions work but when I do it myself it all goes pear shaped/wrong(I am such a noob).
Please could you help with how to for example to write the code below into functions.(like opening the input file).
My attempt:
void outputFile(int argc, char **argv)
{
/* Check that the output file doesnt exist */
if (stat(argv[argc-1], &inode) != -1)
{
printf("Warning: The file %s already exists. Not going to overwrite\n", argv[argc-1]);
return -1;
}
/*Opening ouput files*/
file_desc_out = open(argv[i],O_CREAT | O_WRONLY | O_EXCL , S_IRUSR|S_IWUSR);
if(file_desc_out == -1)
{
printf("Error: %s cannot be opened. \n",argv[i]); //insted of argv[2] have pointer i.
return -1;
}
}
Any help on how I would now reference to this in my program is appreciated thank you.
I tried:
ouputfile(but I cant figure out what goes here and why either).
