/* NAME
/* quote_flags 3
/* SUMMARY
/* quote rfc 821/822 local part
/* SYNOPSIS
/* #include <quote_flags.h>
/*
/* int quote_flags_from_string(const char *string)
/*
/* const char *quote_flags_to_string(VSTRING *res_buf, int mask)
/* DESCRIPTION
/* quote_flags_from_string() converts symbolic flag names into
/* the corresponding internal bitmask. This logs a warning and
/* returns zero if an unknown symbolic name is specified.
/*
/* quote_flags_to_string() converts from internal bitmask to
/* the corresponding symbolic names. This logs a warning and
/* returns a null pointer if an unknown bitmask is specified.
/*
/* Arguments:
/* .IP string
/* Symbolic representation of a quote_flags bitmask, for
/* example: \fB8bitclean | bare_localpart\fR. The conversion
/* is case-insensitive.
/* .IP res_buf
/* Storage for the quote_flags_to_string() result, which has
/* the same form as the string argument. If a null pointer is
/* specified, quote_flags_to_string() uses storage that is
/* overwritten with each call.
/* .IP mask
/* Binary representation of quote_flags.
/* DIAGNOSTICS
/* Fatal error: out of memory; or unknown bitmask name or value.
