 _retc()
 Post a character return value using a null-terminated string
------------------------------------------------------------------------------
 C Prototype

     #include "extend.api"
     void _retc(
                 char far * fpString
               )

 Arguments

     fpString is a far pointer to the null-terminated string whose
     contents are to be returned as a character value.

 Returns

     _retc() has no return value.

 Description

     _retc() posts a character value into CA-Clipper's return value area.
     When your Extend routine returns control to the calling CA-Clipper
     program, the posted value becomes the CA-Clipper return value of your
     Extend routine.

     _retc() determines the logical length of the character value by scanning
     the supplied string for a null terminator byte.  If you are returning
     binary data that may contain embedded null bytes, use _retclen()
     instead.

     Note:  _retc() automatically allocates memory in the CA-Clipper heap
     and makes a copy of the supplied string.  The string need not be
     preserved after the call to _retc().

 Examples

     .  From C:

        _retc("hello world");

     .  From Assembly language:

        EXTRN __retc:FAR
              mov   dx, seg MyString     ; pass address of string
                                         ; (creation of string not shown)
              mov   ax, offset MyString
              push  dx
              push  ax
              call  __retc
              add   sp, 4                ; reset stack pointer
