.Nd functions to query OpenRC service configurations
.Sh LIBRARY

.In rc.h
.Ft "RC_STRINGLIST *" Fn rc_config_list "const char *file"
.Ft "RC_STRINGLIST *" Fn rc_config_load "const char *file"
.Ft "char *" Fn rc_config_value "const char *const *list" "const char *entry"
.Ft bool Fn rc_yesno "const char *value"
.Sh DESCRIPTION
These functions provide an easy means of querying OpenRC configuration files.
.Pp
.Fn rc_config_list
returns a list of non comment lines in

.Fn rc_config_load
does the same, but attempts to parse the line as if it was
a shell assignment.
.Fn rc_config_value
returns the value of
.Fa entry
found in
.Fa list .
.Pp
Each list should be freed using
.Fn rc_stringlist_free
when done.
.Pp
.Fn rc_yesno
returns if
.Fa value
is true, yes, on or 1 regardless of case, otherwise false.
If
.Fa value
is also not false, no, off or 0 regardless of case then
.Va errno
is set to
.Va EINVAL .
