Config Module

The Config module is responsible for managing the application’s configuration. It reads configuration from an .ini file and stores it in a config_t structure. The configuration includes settings for PostgreSQL and SMTP.

Configuration File

The configuration is stored in an .ini file. This file is divided into sections, each representing a different part of the configuration. Here’s an example:

[postgres]
enabled = true
origin_host = localhost
origin_user = user
origin_password = password
origin_port = 5432
origin_db = database

[smtp]
username = user
password = password
smtp_host = smtp.example.com
smtp_port = 587
auth_mode = login

In this example, the [postgres] section contains the configuration for PostgreSQL, and the [smtp] section contains the configuration for SMTP.

config_t Structure

The config_t structure holds the application’s configuration. It includes fields for PostgreSQL and SMTP configuration:

typedef struct {
    postgres_t *postgres;
    smtp_t *smtp;
} config_t;

The postgres_t and smtp_t structures represent the PostgreSQL and SMTP configuration, respectively.

Accessing the Configuration

The configuration is stored in a global config_t variable. You can access this variable to read the configuration:

extern config_t *config;

For example, to get the PostgreSQL username, you would use config→postgres→origin_user.

Updating the Configuration

To update the configuration, you need to modify the .ini file and restart the application. The Config module will read the new configuration when the application starts.
