◆ derive_file_spec()

bool derive_file_spec ( char * file_spec,
char * dir,
char * file_name )

Derive full file specification from directory and file name.

Parameters
file_spec- output full file specification
dir- directory path
file_name- file name
Returns
true if file_spec is derived, false otherwise
Note
If dir is nullptr, use MAPP_DIR environment variable or default directory ~/menuapp
file_spec should be a pre-allocated char array of size MAXLEN to hold the resulting file specification

◆ write_config()

int write_config ( Init * init)

Write the current configuration to a file specified in init->minitrc.

Parameters
init- pointer to Init struct containing current configuration
Returns
0 on success, -1 on failure
Note
The configuration is written in key=value format, one per line
Lines beginning with '#' are comments and are ignored when reading the config file
The file is created if it does not exist, and overwritten if it does exist

◆ zero_opt_args()

void zero_opt_args ( Init * init)

Initialize optional arguments in the Init struct to default values.

Parameters
init- pointer to Init struct to be initialized This function sets all optional argument fields in the Init struct to their default values before parsing command-line options or configuration file. This ensures that any fields not specified by the user will have known default values.
