NAME DtEditorSetContentsFromFile - load data from a file into a DtEditor widget SYNOPSIS #include <Dt/Editor.h> DtEditorErrorCode DtEditorSetContentsFromFile(Widget widget, char *fileName); DESCRIPTION The DtEditorSetContentsFromFile() function loads the con- tents of a file into a DtEditor widget. Any data currently in the DtEditor widget is lost. After the data is loaded, the insertion cursor is positioned at the first character. The widget argument specifies the DtEditor widget ID. The fileName argument is the pathname of the file relative to the local system. For a complete definition of the DtEditor widget and its associated resources, see DtEditor(3). RETURN VALUE Upon successful completion, the DtEditorSetContentsFrom- File() function returns one of the following values when it successfully loads the data into the DtEditor widget: DtEDITOR_NO_ERRORS The file is readable and writable. DtEDITOR_READ_ONLY_FILE The file is read only. DtEDITOR_NULLS_REMOVED The file contained embedded NULL characters, which were removed. Otherwise, if it cannot load the data into the DtEditor widget, the function returns one of the following values: DtEDITOR_NONEXISTENT_FILE The file does not exist. DtEDITOR_DIRECTORY The file is a directory. DtEDITOR_CHAR_SPECIAL_FILE The file is a character-special device. DtEDITOR_BLOCK_MODE_FILE The file is a block-mode device.
