Is there a system call other than 'open' for opening very large files?
Dear all,
Inside a C program, I want to open a very big file (about 12 GB) in order to read its
content. Here is the code:
Code:
/*
argv[1] contains the path to the file.
*/
inputFileDescriptor = open(argv[1], O_RDONLY);
if (inputFileDescriptor < 0)
{
fprintf(stderr, "Error: Could not open the input file\n");
fprintf(stderr, "%s\n", strerror(errno));
return 1;
}
And it seems that the file is too big, because I receive the following error message:
Code:
Error: Could not open the input file
Value too large for defined data type
Is there any other system call, allowing to open very big files?

My understanding is that raw volumes are not cached and I assumed that the ramdisk is not either. Am... (1 Reply)

When the programmer use 'open' function, the process is like below.
"open -> system call wrapper of open in Glibc -> syscall_open in kernel"
I found the wrapper of open, but there is no implementation like 'int $80'.

const char *file;

paps
PAPS(1) General Commands Manual PAPS(1)NAME
paps - UTF-8 to PostScript converter using Pango
SYNOPSIS
paps [options] files...
DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
through the pango ft2 backend.
OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is
included below.
--landscape
Landscape output. Default is portrait.
--columns=cl
Number of columns output. Default is 1.
--font=desc
Set the font description. Default is Monospace 12.
--rtl Do rtl layout.
--paper ps
Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.
--bottom-margin=bm
Set bottom margin in postscript points (1/72 inch). Default is 36.
--top-margin=tm
Set top margin. Default is 36.
--left-margin=lm
Set left margin. Default is 36.
--right-margin=rm
Set right margin. Default is 36.
--help Show summary of options.
--header
Draw page header for each page.
--markup
Interpret the text as pango markup.
--encoding=ENCODING
Assume the documentation encoding is ENCODING.
--lpi Set the lines per inch. This determines the line spacing.
--cpi Set the characters per inch. This is an alternative method of specifying the font size.
--stretch-chars
Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
behaviour.
