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)

XmTextGetSubstring(library call) XmTextGetSubstring(library call)
NAME
XmTextGetSubstring -- A Text function that retrieves a copy of a portion of the internal text buffer
SYNOPSIS
#include <Xm/Text.h>
int XmTextGetSubstring(
Widget widget,
XmTextPosition start,
int num_chars,
int buffer_size,
char *buffer);
DESCRIPTION
XmTextGetSubstring retrieves a copy of a portion of the internal text buffer of a Text 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 following
equation to calculate the size of buffer the application should provide:
buffer_size = (num_chars* MB_CUR_MAX) + 1
(void)
widget Specifies the Text widget ID.
start 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 (zero).
num_chars Specifies the number of characters to be copied into the provided buffer.
buffer_size
Specifies the size of the supplied buffer in bytes. This size should account for a NULL terminator.
buffer Specifies the character buffer into which the internal text buffer will be copied.
For a complete definition of Text and its associated resources, see XmText(3).
RETURN
XmCOPY_SUCCEEDED
The function was successful.
XmCOPY_FAILED
The function failed because it was unable to copy the specified number of characters into the buffer provided. The buffer size
may be insufficient. The contents of buffer are undefined.
XmCOPY_TRUNCATED
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.
