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`(in char[] `aa`, dg_t `dg`);
int `_aApplyRwd1`(in wchar[] `aa`, dg_t `dg`);
int `_aApplyRcw1`(in char[] `aa`, dg_t `dg`);
int `_aApplyRwc1`(in wchar[] `aa`, dg_t `dg`);
int `_aApplyRdc1`(in dchar[] `aa`, dg_t `dg`);
int `_aApplyRdw1`(in dchar[] `aa`, dg_t `dg`);
  Same as _aApplyXXX functions, but for foreach_reverse
  Parameters:

  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`(in char[] `aa`, dg2_t `dg`);
int `_aApplyRwd2`(in wchar[] `aa`, dg2_t `dg`);
int `_aApplyRcw2`(in char[] `aa`, dg2_t `dg`);
int `_aApplyRwc2`(in wchar[] `aa`, dg2_t `dg`);
int `_aApplyRdc2`(in dchar[] `aa`, dg2_t `dg`);
int `_aApplyRdw2`(in dchar[] `aa`, dg2_t `dg`);
  Variants of aApplyRXXX that include a loop index.
