pack_fread(3alleg4) Allegro manual pack_fread(3alleg4)NAME
pack_fread - Reads n bytes from the stream. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
long pack_fread(void *p, long n, PACKFILE *f);
DESCRIPTION
Reads `n' bytes from the stream `f', storing them at the memory location pointed to by `p'. Example:
unsigned char buf[256];
...
if (pack_fread(buf, 256, input_file) != 256)
abort_on_error("Truncated input file!");
RETURN VALUE
Returns the number of bytes read, which will be less than `n' if EOF is reached or an error occurs. Error codes are stored in errno.

pack_fgets - Reads a line from the stream. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
char *pack_fgets(char *p, int max, PACKFILE *f);
DESCRIPTION
Reads a line from the stream `f', storing it at location pointed to by `p'. Stops when a linefeed is encountered, or `max' bytes have been
read. The end of line is handled by detecting the right combination of characters for the platform. This supports CR-LF (DOS/Windows), LF
(Unix), and CR (Mac) formats. However, the trailing carriage return is not included in the returned string, in order to provide easy code
portability across platforms. If you need the carriage return, use pack_fread() and/or pack_getc() instead.
Note: This function internally may make calls to pack_ungetc, so you cannot use pack_ungetc directly afterwards.
Example:
char buf[256];
...
while (pack_fgets(buf, sizeof(buf), input_file)) {
/* Process input line. */
}
fclose(input_file);
RETURN VALUE
Returns the pointer `p' on success, or NULL on error.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.

Hi all...
Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.
Many tricky terminal escape codes are not catered for so I had to create workarounds.
One thing I searched for was this:

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).

This is purely a fun project to see if it is possible in PURE... (3 Replies)
