I'm trying to write an integer to a file using the write() function, but write() requires the parameter to be written to be a const void*.
How would I go about doing this?
also: using itoa() produces a " warning: implicit declaration of function 'itoa' " even though i have #included stdlib.h (2 Replies)

I would like to add 4.7 and 1.2. However I am unable to do this with expr.
Any simple ideas (even using something other than expr)?
Example:
me> expr 4 + 1
5
me> expr 4.7 + 1.2
expr: 0402-046 A specified operator requires numeric parameters. (18 Replies)

Wonderful evening to all of you!
My problem has to possible starting points.
Well, not really, but getting to either one is no problem at all.

I have a directory with a bunch of files in it. The files are named xinteger_yinteger_zinteger.vtk (eg, x3_y0_z-1.vtk). I want to read the filenames and then assign the integers to variables that I then can use in expressions. So, for... (6 Replies)
Hi,
I can't figure out what I'm missing. I'm running a query to see if there are any streams recording on my DVR before starting a scripted update.

Locale::Codes::LangFam(3pm) Perl Programmers Reference Guide Locale::Codes::LangFam(3pm)NAME
Locale::Codes::LangFam - standard codes for language extension identification
SYNOPSIS
use Locale::Codes::LangFam;
$lext = code2langfam('apa'); # $lext gets 'Apache languages'
$code = langfam2code('Apache languages'); # $code gets 'apa'
@codes = all_langfam_codes();
@names = all_langfam_names();
DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
ISO 639-5.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
language family codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
constant that is automatically exported by this module.
For example, the two are equivalent:
$lext = code2langfam('apa','alpha');
$lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);
The codesets currently supported are:
alpha
This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.
This is the default code set.
ROUTINES
code2langfam ( CODE [,CODESET] )
langfam2code ( NAME [,CODESET] )
langfam_code2code ( CODE ,CODESET ,CODESET2 )
all_langfam_codes ( [CODESET] )
all_langfam_names ( [CODESET] )
Locale::Codes::LangFam::rename_langfam ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangFam::add_langfam ( CODE ,NAME [,CODESET] )
Locale::Codes::LangFam::delete_langfam ( CODE [,CODESET] )
Locale::Codes::LangFam::add_langfam_alias ( NAME ,NEW_NAME )
Locale::Codes::LangFam::delete_langfam_alias ( NAME )
Locale::Codes::LangFam::rename_langfam_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangFam::add_langfam_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangFam::delete_langfam_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
