        <pre>According to C99 5.1.2.2.1:

2.

If they [argc, argv] are declared, the parameters to the main function shall

obey the following constraints:

— The value of argc shall be nonnegative.

— argv[argc] shall be a null pointer.

— If the value of argc is greater than zero, the array members argv[0] through

argv[argc-1] inclusive shall contain pointers to strings, which are given

implementation-deﬁned values by the host environment prior to program startup.

The intent is to supply to the program information determined prior to program

startup from elsewhere in the hosted environment. If the host environment is

not capable of supplying strings with letters in both uppercase and lowercase,

the implementation

shall ensure that the strings are received in lowercase.

— If the value of argc is greater than zero, the string pointed to by argv[0]

represents the program name; argv[0][0] shall be the null character if the

program name is not available from the host environment. If the value of argc

is

greater than one, the strings pointed to by argv[1] through argv[argc-1]

represent the program parameters.

— The parameters argc and argv and the strings pointed to by the argv array

shall

be modiﬁable by the program, and retain their last-stored values between

program

startup and program termination.

So, the location of the arguments are implementation defined and it's pretty

fine to pass them on heap.</pre>
