Function Documentation

   size_t wget_vasprintf (char ** strp, const char * fmt, va_list args)
       Parameters:
           strp Pointer to hold the string output
           fmt Printf-like format specifier
           args va_list of arguments

       Returns:
           Length of the string returned via strp

       Prints arguments to allocated memory and 0-terminates it. The string is returned via the
       first argument. It has to be free()'d by the caller when it is no longer needed.

   size_t wget_asprintf (char ** strp, const char * fmt,  ...)
       Parameters:
           strp Pointer to hold the string output
           fmt Printf-like format specifier
           ... List of arguments

       Returns:
           Length of the string returned via strp

       Prints arguments to allocated memory and 0-terminates it. The string is returned via the
       first argument. It has to be free()'d by the caller when it is no longer needed.

   char* wget_vaprintf (const char * fmt, va_list args)
       Parameters:
           fmt Printf-like format specifier
           args va_list of arguments

       Returns:
           Pointer to 0-terminated string in memory

       Prints arguments to memory and returns a pointer to allocated and 0-terminated chunk of
       memory. The return value has to be free()'d by the caller when it is no longer needed.

   char* wget_aprintf (const char * fmt,  ...)
       Parameters:
           fmt Printf-like format specifier
           ... List of arguments

       Returns:
           Pointer to 0-terminated string in memory

       Prints arguments to memory and returns a pointer to allocated and 0-terminated chunk of
