Command line arguments: use of space between program argument, and the argument's argument
Tag : c , By : jumpingmattflash

like below fixes the issue argv contains an array of strings. Argv[0] contains the program name, argv[1] contains -f in your case, argv[2] contains filename. If you print argv[1][3], you are printing the string starting at the third letter of -f. There is no such thing, so the behavior is undefined.

How do I access a specific argument without knowing it's type [variable arguments] in C?

help you fix your problem There is no portable standard way to know what the types are. The first solution that comes to mind is to use the already well-known C idiom of having to pass a format string (e.g. printf, scanf). void write_log(FILE * fp, char * event, const char* fmt, ...)
{
va_list list;
va_start(list, event);
// process fmt and act accordingly
}
enum type {
integer,
pointer,
floating
};
void write_log(FILE * fp, char * event, enum type t, ...)
{
switch(t)
{
case integer: // do stuff with integer
case pointer: // do stuff with pointer
}
}
void write_logi(FILE * fp, char * event, int);
void write_logf(FILE * fp, char * event, float);
void write_logfoo(FILE * fp, char * event, struct foo);
#define write_log(file, event, arg) _Generic((arg), \
int: write_logi, \
float: write_logf, \
struct foo: write_logfoo \
)(file, event, arg)
write_log(fp, event, i/*int*/);
write_log(fp, event, f/*float*/);
