.Sh DESCRIPTION
These functions provide an easy means of querying OpenRC configuration files.
.Pp
.Fn rc_getline
expands it's buffer using
.Fn malloc
until it has read a whole line from the file or EOF.
Trailing newlines are removed and the buffer is returned. Any functions that
read from files should use this function to avoid any potential overflows and
to ensure that arbitary long lines are read.
.Pp
.Fn rc_config_list
returns a list of non comment lines in
.Fa file .
