hook_config_section(3alleg4)					  Allegro manual				      hook_config_section(3alleg4)

NAME
       hook_config_section - Hooks a configuration file section with custom handlers. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void  hook_config_section(const	char  *section, int (*intgetter)(const char *name, int def), const char *(*stringgetter)(const char *name,
       const char *def), void (*stringsetter)(const char *name, const char *value));

DESCRIPTION
       Takes control of the specified config file section, so that your hook functions will be used to manipulate it instead of  the  normal  disk
       file access. If both the getter and setter functions are NULL, a currently present hook will be unhooked. Hooked functions have the highest
       priority. If a section is hooked, the hook will always be called, so you can also hook a '#' section:  even  override_config_file()  cannot
       override a hooked section. Example:

	  int decode_encrypted_int(const char *name, int def)
	  {
	     ...
	  }

	  const char *decode_encrypted_string(const char *name, const char *def)
	  {
	     ...
	  }

	  void encode_plaintext_string(const char *name, const char *value)
	  {
	     ...
	  }

	  int main(int argc, char *argv[])
	  {
	     ...
	     /* Make it harder for users to tinker with the high scores. */
	     hook_config_section("high_scores", decode_encrypted_int,
		decode_encrypted_string, encode_plaintext_string);
	     ...
	  } END_OF_MAIN()
