Hi All,
My main intension of is to convert the Hexstring stored in a char* into hex and then prefixing it with "0x" and suffix it with ','
This has to be done for all the hexstring char* is NULL.
Store the result prefixed with "0x" and suffixed with ',' in another char* and pass it to... (1 Reply)
Hi,
Is there really a difference between these two, std::hex and ios::hex??
I stumbled upon reading a line, "std::ios::hex is a bitmask (8 on gcc) and works with setf(). std::hex is the operator". Is this true?
Thanks (0 Replies)
Hi,
I want to split/parse certain bits of the hex data into another field.
Example:
Input data is
Word1: 4f72abfd
Output:
Parse bits (5 to 0) into field word1data1=0x00cd=205 decimal
Parse bits (7 to 6) into field word1data2=0x000c=12 decimal
etc.
Word2: efff3d02
Parse bits (13 to... (1 Reply)

Hi guys,
First off, i'm a complete noob to UNIX and LINUX so apologies if I don't understand the basics!
I have a file which contains a hex value of '0D' at the end of each line when I look at it in a hex viewer.
I need to change it so it contains a hex value of '0D0A0A'
I thought... (10 Replies)
dHi,
I have the attached file(actual file can be extracted post unzipping it) & i am trying to use the following code for coversion to hex format.
Starting hex value is 84 which is start of the record & termination is done using 00 00 followed by 84(hex) which i can see in the dump clearly using... (14 Replies)

stdio
STDIO(3) Library Functions Manual STDIO(3)NAME
stdio - standard buffered input/output package
SYNOPSIS
#include <stdio.h>
FILE *stdin;
FILE *stdout;
FILE *stderr;
DESCRIPTION
The functions in the standard I/O library constitute a user-level buffering scheme. The in-line macros getc and putc(3) handle characters
quickly. The higher level routines gets, fgets, scanf, fscanf, fread, puts, fputs, printf, fprintf, fwrite all use getc and putc; they can
be freely intermixed.
A file with associated buffering is called a stream, and is declared to be a pointer to a defined type FILE. Fopen(3) creates certain
descriptive data for a stream and returns a pointer to designate the stream in all further transactions. There are three normally open
streams with constant pointers declared in the include file and associated with the standard open files:
stdin standard input file
stdout standard output file
stderr standard error file
A constant `pointer' NULL (0) designates no stream at all.
An integer constant EOF (-1) is returned upon end of file or error by integer functions that deal with streams.
Any routine that uses the standard input/output package must include the header file <stdio.h> of pertinent macro definitions. The func-
tions and constants mentioned in the standard I/O manual pages are declared in the include file and need no further declaration. The con-
stants, and the following `functions' are implemented as macros; redeclaration of these names is perilous: clearerr, getc, getchar, putc,
putchar, feof, ferror, fileno.
SEE ALSO open(2), close(2), read(2), write(2), fclose(3), ferror(3), fopen(3), fread(3), fseek(3), getc(3), gets(3), printf(3), putc(3), puts(3),
scanf(3), setbuf(3), ungetc(3).
DIAGNOSTICS
The value EOF is returned uniformly to indicate that a FILE pointer has not been initialized with fopen, input (output) has been attempted
on an output (input) stream, or a FILE pointer designates corrupt or otherwise unintelligible FILE data.
For purposes of efficiency, this implementation of the standard library has been changed to line buffer output to a terminal by default and
attempts to do this transparently by flushing the output whenever a read(2) from the standard input is necessary. This is almost always
transparent, but may cause confusion or malfunctioning of programs which use standard i/o routines but use read(2) themselves to read from
the standard input.
In cases where a large amount of computation is done after printing part of a line on an output terminal, it is necessary to fflush(3) the
standard output before going off and computing so that the output will appear.
BUGS
The standard buffered functions do not interact well with certain other library and system functions, especially fork and abort.
