Detailed Description

Check if an option was explicitly set via command-line.

Simple macro to check if an option was explicitly provided by the user (as opposed to using a default value).

Explicit tracking fields are stored directly in options_t as ${optionName}_explicit. Only frequently-checked options have explicit tracking to avoid struct bloat.

Usage

// Check if user explicitly set an option
if (IS_OPTION_EXPLICIT("splash_screen", opts)) {
    printf("User explicitly set splash_screen\n");
}
