Source rt/aApplyR.d

alias `dg_t` = int delegate(void* c);
  Delegate type corresponding to transformed loop body
  The parameter is a pointer to the current char, wchar or dchar
  Returns:
  non-zero when a break statement is hit
int `_aApplyRcd1`(scope const(char)[] `aa`, dg_t `dg`);
int `_aApplyRwd1`(scope const(wchar)[] `aa`, dg_t `dg`);
int `_aApplyRcw1`(scope const(char)[] `aa`, dg_t `dg`);
int `_aApplyRwc1`(scope const(wchar)[] `aa`, dg_t `dg`);
int `_aApplyRdc1`(scope const(dchar)[] `aa`, dg_t `dg`);
int `_aApplyRdw1`(scope const(dchar)[] `aa`, dg_t `dg`);
  Same as _aApplyXXX functions, but for foreach_reverse
  Parameters:

  const(char)[] `aa` | input string
  dg_t `dg` | foreach body transformed into a delegate, similar to opApply

  Returns:
  non-zero when the loop was exited through a break
alias `dg2_t` = int delegate(void* i, void* c);
  Delegate type corresponding to transformed loop body
  Parameters are pointers to a size_t loop index, and the current char, wchar or dchar.
  Returns:
  non-zero when a break statement is hit
int `_aApplyRcd2`(scope const(char)[] `aa`, dg2_t `dg`);
int `_aApplyRwd2`(scope const(wchar)[] `aa`, dg2_t `dg`);
int `_aApplyRcw2`(scope const(char)[] `aa`, dg2_t `dg`);
int `_aApplyRwc2`(scope const(wchar)[] `aa`, dg2_t `dg`);
int `_aApplyRdc2`(scope const(dchar)[] `aa`, dg2_t `dg`);
int `_aApplyRdw2`(scope const(dchar)[] `aa`, dg2_t `dg`);
  Variants of aApplyRXXX that include a loop index.
