bionic (3) hook_config_section.3alleg4.gz

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()
