.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fB\s-1UI_STRING\s0\fR gets created internally and added to a \fB\s-1UI\s0\fR whenever
one of the functions \fBUI_add_input_string()\fR, \fBUI_dup_input_string()\fR,
\&\fBUI_add_verify_string()\fR, \fBUI_dup_verify_string()\fR,
\&\fBUI_add_input_boolean()\fR, \fBUI_dup_input_boolean()\fR, \fBUI_add_info_string()\fR,
\&\fBUI_dup_info_string()\fR, \fBUI_add_error_string()\fR or \fBUI_dup_error_string()\fR
is called.
For a \fB\s-1UI_METHOD\s0\fR user, there's no need to know more.
For a \fB\s-1UI_METHOD\s0\fR creator, it is of interest to fetch text from these
\&\fB\s-1UI_STRING\s0\fR objects as well as adding results to some of them.
.PP
\&\fBUI_get_string_type()\fR is used to retrieve the type of the given
\&\fB\s-1UI_STRING\s0\fR.
.PP
\&\fBUI_get_input_flags()\fR is used to retrieve the flags associated with the
given \fB\s-1UI_STRING\s0\fR.
.PP
\&\fBUI_get0_output_string()\fR is used to retrieve the actual string to
output (prompt, info, error, ...).
.PP
\&\fBUI_get0_action_string()\fR is used to retrieve the action description
associated with a \fB\s-1UIT_BOOLEAN\s0\fR type \fB\s-1UI_STRING\s0\fR.
For all other \fB\s-1UI_STRING\s0\fR types, \s-1NULL\s0 is returned.
See \fBUI_add_input_boolean\fR\|(3).
.PP
\&\fBUI_get0_result_string()\fR and \fBUI_get_result_string_length()\fR are used to
retrieve the result of a prompt and its length.
This is only useful for \fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type strings.
For all other \fB\s-1UI_STRING\s0\fR types, \fBUI_get0_result_string()\fR returns \s-1NULL\s0
and \fBUI_get_result_string_length()\fR returns \-1.
.PP
\&\fBUI_get0_test_string()\fR is used to retrieve the string to compare the
prompt result with.
This is only useful for \fB\s-1UIT_VERIFY\s0\fR type strings.
For all other \fB\s-1UI_STRING\s0\fR types, \s-1NULL\s0 is returned.
.PP
\&\fBUI_get_result_minsize()\fR and \fBUI_get_result_maxsize()\fR are used to
retrieve the minimum and maximum required size of the result.
This is only useful for \fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type strings.
For all other \fB\s-1UI_STRING\s0\fR types, \-1 is returned.
.PP
\&\fBUI_set_result_ex()\fR is used to set the result value of a prompt and its length.
For \fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type \s-1UI\s0 strings, this sets the
result retrievable with \fBUI_get0_result_string()\fR by copying the
contents of \fBresult\fR if its length fits the minimum and maximum size
requirements.
For \fB\s-1UIT_BOOLEAN\s0\fR type \s-1UI\s0 strings, this sets the first character of
the result retrievable with \fBUI_get0_result_string()\fR to the first
\&\fBok_char\fR given with \fBUI_add_input_boolean()\fR or \fBUI_dup_input_boolean()\fR
if the \fBresult\fR matched any of them, or the first of the
\&\fBcancel_chars\fR if the \fBresult\fR matched any of them, otherwise it's
set to the \s-1NUL\s0 char \f(CW\*(C`\e0\*(C'\fR.
See \fBUI_add_input_boolean\fR\|(3) for more information on \fBok_chars\fR and
\&\fBcancel_chars\fR.
.PP
\&\fBUI_set_result()\fR does the same thing as \fBUI_set_result_ex()\fR, but calculates
its length internally.
It expects the string to be terminated with a \s-1NUL\s0 byte, and is therefore
only useful with normal C strings.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBUI_get_string_type()\fR returns the \s-1UI\s0 string type.
.PP
\&\fBUI_get_input_flags()\fR returns the \s-1UI\s0 string flags.
.PP
\&\fBUI_get0_output_string()\fR returns the \s-1UI\s0 string output string.
.PP
\&\fBUI_get0_action_string()\fR returns the \s-1UI\s0 string action description
string for \fB\s-1UIT_BOOLEAN\s0\fR type \s-1UI\s0 strings, \s-1NULL\s0 for any other type.
.PP
\&\fBUI_get0_result_string()\fR returns the \s-1UI\s0 string result buffer for
\&\fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type \s-1UI\s0 strings, \s-1NULL\s0 for any other
type.
.PP
\&\fBUI_get_result_string_length()\fR returns the \s-1UI\s0 string result buffer's
content length for \fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type \s-1UI\s0 strings,
\&\-1 for any other type.
.PP
\&\fBUI_get0_test_string()\fR returns the \s-1UI\s0 string action description
string for \fB\s-1UIT_VERIFY\s0\fR type \s-1UI\s0 strings, \s-1NULL\s0 for any other type.
.PP
\&\fBUI_get_result_minsize()\fR returns the minimum allowed result size for
the \s-1UI\s0 string for \fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type strings,
\&\-1 for any other type.
.PP
\&\fBUI_get_result_maxsize()\fR returns the minimum allowed result size for
the \s-1UI\s0 string for \fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type strings,
\&\-1 for any other type.
.PP
\&\fBUI_set_result()\fR returns 0 on success or when the \s-1UI\s0 string is of any
type other than \fB\s-1UIT_PROMPT\s0\fR, \fB\s-1UIT_VERIFY\s0\fR or \fB\s-1UIT_BOOLEAN\s0\fR, \-1 on
error.
