assigns a value to the CF variable in CTX. The NBSP;NBSP;NBSP;NBSP;NBSP;NBSP;NBSP;CF variable is of type Conf.

Conf_create sets the function pointers and parsing types in CF first, then processes them, and finally saves the processed results in the ARG array of the Conf struct. Note: The contents of the last configuration file are all contained in the ARG arr
