.SH NAME
stringprep_4zi \- API function
.SH SYNOPSIS
.B #include <stringprep.h>
.sp
.BI "int stringprep_4zi(uint32_t * " ucs4 ", size_t " maxucs4len ", Stringprep_profile_flags " flags ", const Stringprep_profile * " profile ");"
.SH ARGUMENTS
.IP "uint32_t * ucs4" 12
input/output array with zero terminated string to prepare.
.IP "size_t maxucs4len" 12
maximum length of input/output array.
.IP "Stringprep_profile_flags flags" 12
a \fBStringprep_profile_flags\fP value, or 0.
.IP "const Stringprep_profile * profile" 12
pointer to \fBStringprep_profile\fP to use.
.SH "DESCRIPTION"
Prepare the input zero terminated UCS\-4 string according to the
stringprep profile, and write back the result to the input string.

Since the stringprep operation can expand the string,  \fImaxucs4len\fP indicate how large the buffer holding the string is.  This function
will not read or write to code points outside that size.

The  \fIflags\fP are one of \fBStringprep_profile_flags\fP values, or 0.

The  \fIprofile\fP contain the \fBStringprep_profile\fP instructions to
perform.  Your application can define new profiles, possibly
re\-using the generic stringprep tables that always will be part of
the library, or use one of the currently supported profiles.

Return value: Returns \fBSTRINGPREP_OK\fP iff successful, or an
\fBStringprep_rc\fP error code.
