nstd_std_env_free_path^⚠

Frees memory allocated by nstd_std_env_path_to_exe, nstd_std_env_current_dir or nstd_std_env_temp_dir. Parameters: char **path - String from nstd_std_env_path_to_exe or nstd_std_env_current_dir.

nstd_std_env_free_var^⚠

Frees memory allocated by nstd_std_env_get_var. Parameters: char **v - The value returned from nstd_std_env_get_var.

nstd_std_env_free_vars^⚠

Frees memory allocated by nstd_std_env_vars. Parameters: char **vars - Returned from nstd_std_env_vars.

nstd_std_env_get_var^⚠

Gets an environment variable. Parameters: const char *const k - The var key. Returns: char *v - The value of the variable.
