Function Documentation

quad_toggle()

static int quad_toggle ( int  opt )

static

Toggle (invert) the value of a quad option.

Parameters

opt	Value to toggle

Return values

num

New value

By toggling the low bit, the following are swapped:

• MUTT_NO <--> MUTT_YES
• MUTT_ASKNO <--> MUTT_ASKYES

Definition at line 190 of file quad.c.

{
  return opt ^= 1;
}

Here is the caller graph for this function:

quad_he_toggle()

int quad_he_toggle	(	struct ConfigSubset *	sub,
		struct HashElem *	he,
		struct Buffer *	err
	)

Toggle the value of a quad.

Parameters

sub	Config subset
he	HashElem representing config item
err	Buffer for error messages

Return values

num	Result, e.g. CSR_SUCCESS

Variable Documentation

QuadValues

const char* QuadValues[]

Initial value:

= {
  "no", "yes", "ask-no", "ask-yes", NULL,

CstQuad

const struct ConfigSetType CstQuad

Initial value:

= {
  DT_QUAD,
  "quad",
  quad_string_set,
  quad_string_get,
  quad_native_set,
  quad_native_get,
  NULL, 
  NULL,
