set_config_string(3)            Allegro manual            set_config_string(3)

NAME
       set_config_string - Writes a string in the configuration file. Allegro
       game programming library.

SYNOPSIS
       #include <allegro.h>

       void set_config_string(const char *section, const char *name, const
       char *val);

DESCRIPTION
       Writes a string variable to the current config file, replacing any
       existing value it may have, or removes the variable if `val' is NULL.
       The section name may be set to NULL to write the variable to the root
       of the file, or used to control which section the variable is inserted
       into. The altered file will be cached in memory, and not actually
       written to disk until you call allegro_exit(). Note that you can only
       write to files in this way, so the function will have no effect if the
       current config source was specified with set_config_data() rather than
       set_config_file().

       As a special case, variable or section names that begin with a '#'
       character are treated specially and will not be read from or written to
       the disk. Addon packages can use this to store version info or other
       status information into the config module, from where it can be read
       with the get_config_string() function.
