bool validate_port_callback	(	const void *	options_struct,

	)

Validate port option callback (matches option_descriptor validate signature) Used during options parsing to validate port values with PCRE2

Definition at line 97 of file validation.c.

                                                                          {
  const options_t *opts = (const options_t *)options_struct;
 
  // Port is stored as an int, but we need to validate it as a string
  // The issue is that strtol() already accepted invalid formats like " 80", "+80", "0123"
  // So we can't validate after parsing - we need to prevent the parse in the first place
  // This callback runs AFTER parsing, so it's too late
 
  // Instead, check if the port value is in range (this will catch the range but not format issues)
  if (opts->port < 1 || opts->port > 65535) {
    if (error_msg) {
      *error_msg = platform_strdup("Port must be between 1 and 65535");
    }
    return false;
  }
 
  return true;
