Hi,
i would like substitute the words containing the character "-" by any other.
i've already tried the tr command: tr '\-' 'X', for example.
But, this command doesn't work. It gave this:
Original text:
-i abcd-fe
Result text:
Xi abcdXfe
Result desired:
-i abcdXfe

dteditorinsert
DtEditorInsert(library call) DtEditorInsert(library call)
NAME
DtEditorInsert -- insert data into a DtEditor widget
SYNOPSIS
#include <Dt/Editor.h>
DtEditorErrorCode DtEditorInsert(
Widget widget,
DtEditorContentRec *data);
DESCRIPTION
The DtEditorInsert function inserts either a string, wide character string or sized buffer at the insertion cursor position in a DtEditor
widget. The data is transferred to the DtEditor widget using a DtEditorContentRec, which indicates the type of data being transferred
along with the actual data. After the data is appended, the insertion cursor is positioned after the last character inserted.
The widget argument specifies the DtEditor widget ID.
The data argument is a pointer to a data structure containing the data to insert.
For a complete definition of the DtEditor widget and its associated resources, see DtEditor(3).
For a complete definition of DtEditorContentRec, see Dt/Editor.h - DtEditor(5).
RETURN VALUE
Upon successful completion, the DtEditorInsert function returns one of the following values:
DtEDITOR_NO_ERRORS
The data was inserted sucessfully.
DtEDITOR_NULLS_REMOVED
NULL characters were found and removed from the data.
Otherwise, if the DtEditorInsert function cannot insert the data into the DtEditor widget, it returns one of the following values:
DtEDITOR_INVALID_TYPE
The Type field is not recognized.
DtEDITOR_ILLEGAL_SIZE
The size of the buffer passed in is negative.
DtEDITOR_NULL_ITEM
The buffer is NULL.
DtEDITOR_INSUFFICIENT_MEMORY
Not enough system memory is available to insert the data.
EXAMPLES
The following code segment sets the contents of a DtEditor widget to ``The quick brown fox.''
Widget editor;
DtEditorContentRec cr;
DtEditorErrorCode status;
char *sampleString1="The brown fox",
*sampleString2=" quick";
cr.type = DtEDITOR_TEXT;
cr.value.string = sampleString1;
status = DtEditorSetContents(editor, &cr);
if (status != DtEDITOR_NO_ERRORS && status != DtEDITOR_NULLS_REMOVED) {
printf("Unable to set contents of the widget
");
} else {
/*
* Move the insertion cursor so it is after the
* letter 'e' in "The".
*/
DtEditorSetInsertionCursorPosition(editor, 2);
cr.type = DtEDITOR_TEXT;
cr.data.string = sampleString2;
status = DtEditorInsert(editor, &cr);
if (status != DtEDITOR_NO_ERRORS)
printf("Unable to insert into the contents of the widget
");
}
APPLICATION USAGE
If the data is in a disk file, rather than in memory, the application should use DtEditorInsertFromFile(3).
