Hi...
I am trying to read a binary data that have different types of messages of different lengths. I am using fread() but this functions needs the size and count to read the buffer from the file. I think this may cause that the buffer overlaps other messages.
Is there an alternative to read... (1 Reply)

XmTextFieldGetSubstring(3X)XmTextFieldGetSubstring(3X)NAME
XmTextFieldGetSubstring - A TextField function that retrieves a copy of a portion of the internal text buffer
SYNOPSIS
#include <Xm/TextF.h>
int XmTextFieldGetSubstring (widget, start, num_chars, buffer_size, buffer)
Widget widget;
XmTextPosition start;
int num_chars;
int buffer_size;
char *buffer;
DESCRIPTION
XmTextFieldGetSubstring retrieves a copy of a portion of the internal text buffer of a TextField widget. The function copies a specified
number of characters from a given start position in the internal text buffer into a buffer provided by the application. A NULL terminator
is placed at the end of the copied data.
The size of the required buffer depends on the maximum number of bytes per character (MB_CUR_MAX) for the current locale. MB_CUR_MAX is a
macro defined in <stdlib.h>. The buffer should be large enough to contain the substring to be copied and a NULL terminator. Use the fol-
lowing equation to calculate the size of buffer the application should provide:
buffer_size = (num_chars * MB_CUR_MAX) + 1 Specifies the TextField widget ID. Specifies the beginning character position from which the
data will be retrieved. This is an integer number of characters from the beginning of the text buffer. The first character position is 0.
Specifies the number of characters to be copied into the provided buffer. Specifies the size of the supplied buffer in bytes. This size
should account for a NULL terminator. Specifies the character buffer into which the internal text buffer will be copied.
For a complete definition of TextField and its associated resources, see XmTextField(3X).
RETURN VALUE
The function was successful. The function failed because it was unable to copy the specified number of characters into the buffer pro-
vided. The buffer size may be insufficient. The contents of buffer are undefined. The requested number of characters extended beyond the
internal buffer. The function copied characters between start and the end of the widget's buffer and terminated the string with a NULL
terminator; fewer than num_chars characters were copied.
