UniNextCompChar()--Advance to Next Composite Character Sequence API

Syntax

  #include <UniChar.h>

  int UniNextCompChar(void *reserved,
                          UniChar *ucs,
                          UniChar     **next_sequence);

  Service Program: QTQULSFN

  Default Public Authority: *USE

  Threadsafe: No

The UniNextCompChar--Advance to Next Composite Character Sequence function locates the next non-combining character in the string ucs.

Authorities and Locks

None.

Parameters

reserved: INPUT; PTR(SPP)
This parameter must be set to null.
ucs: INPUT; PTR(SPP)
The composite character sequence to be analyzed.
next_sequence: OUTPUT; PTR(SPP)
This is set to the next non-combining character.

Return Value

zero: UniNextCompChar function was successful. The value returned in next_sequence is a pointer to the next non-combining character in ucs.
non-zero: UniNextCompChar was not successful and next_sequence is set to the NULL pointer.

Error Conditions

If UniNextCompChar is not successful, the return value indicates one of the following errors:

UNI_BADOBJ	UniNextCompChar function detected that the reserved parameter is not null.
UNI_INVALID	UniNextCompChar function detected that ucs is a null pointer.
UNI_NODATA	UniNextCompChar function detected that ucs points to a null code element.
UNI_COMP_FOUND	UniNextCompChar function detected that ucs points to a combining character. The caller should advance ucs by one UniChar and call the function again until this error no longer occurs.
UNI_RANGE	UniQueryCompCharLen function detected that the value to be set in element_count was too large to fit.
