CPRL_ENCODE_
inputstring
is an array in which CPRL_UPSHIFT_ returns the downshifted string.
inputstringlength
is the number of bytes to be downshifted in inputstring.
shiftedstring
is an array in which CPRL_DOWNSHIFT_ returns the downshifted string.
The values for inputstring and shiftedstring can be equal, but other
values can cause unpredictable results.
shiftedstringmaxlength
specifies the maximum length of shiftedstring; it must be greater than equal to
inputstring.
shiftedstringlength
specifies the length of the downshifted string returned in shiftedstring.
cprladdr
is a pointer to the SQL collation or collation object.
CPRL_ENCODE_
The CPRL_ENCODE_ procedure encodes a character string so that a subsequent
binary comparison produces proper results for the specified SQL collation. Use
CPRL_ENCODE_ in situations where the number of encodings required is
substantially less than the number of comparisons (for example, during a sort).
#include <cextdecs(CPRL_ENCODE_)>

,char *encodedstring /* o */
,short encodedstringmaxlength /* i */
,short *encodedstringlength /* o */
,long cprladdr ); /* i */
