calling free on a char * throwing Segmentation fault
Hey, Thanks for your reply. I was just going over my code again and noticed the same thing!! Arg, stupid mistake! I meant to comment that line out because that was the old way before I used strdup, but forgot to. Thanks for your help, this is a great forum. Later -
calling free on a char * throwing Segmentation fault
Hello, just before my program exits I am trying to free up all malloced memory, however when I try to call free on one of my char * I get a segmentation fault. Here is some of my code. Here is my structure....it is a linked list: //this is a structure for our file information struct... -
free and malloc question
Thanks for the answer. So just to be clear, if I don't call free on all my malloced pointers when the program ends the OS will "probably" free up the memory for me anyway, but I should really do it myself just in case another program calls my program. Plus it is just good coding practices... -
free and malloc question
...eaten up each time I run my program? Do give you an idea of the code: //this is a structure for our file information struct file_info { char *filename;//name of the file unsigned long matches; // struct line_info * struct file_info *next; //the next file } files; /* So I... -

set focus on text box after validation
Hey, You seem to have extra { and } in there. But to set a fields focus you would do this field.focus(); with field being a reference to the field object for example: document.formname.txtActRevenue; Hope that helps. Later- dwhalen

Are you looking for someone to do this for you or do you want to know how to do it? Because your problem isn't that difficult for someone who knows how to use perl,databases,apache,server configuration ....and many other things but this isn't something that can be solved by someone just posting... -
Attempt to free unreferenced scalar:
Hey, We just updated our Perl 5.6.0 to version 5.8.2 and this error keeps coming up in the Apache error_log: Attempt to free unreferenced scalar: SV 0x8cbb26c at /usr/local/lib/perl5/site_perl/5.8.2/mach/Apache/Registry.pm line 149. Sometimes it is different modules other than Registry.pm... -
Getting current line number
Hey, Sorry I didn't respond sooner but I took yesterday off :). The caller thing works great! Thanks for the help everyone. Later -
Getting current line number
Yeah, I thought the same thing but that gives you the line number of the current opened file handle....close but no cigar :) Thanks Later -
Getting current line number
Hey, I am trying to write personal error_log for a perl program I wrote. What I want in the error_log is the line number where the error occured, the file name and the error message. I know how to get the file name ($0), and I will send my own text message, but is there anyway to get what... -
Digest::MD5 help
hehehe...yeah, I just wanted to give an idea of how I was comparing and where it was failing. As for the new line character, well I have thought of that but I dismissed it because the password is hardcoded on both the dev system and the production system in a file that is called from cron. For... -
Digest::MD5 help
Hello, I work on a web application that uses md5_hex to store and verify passwords. I needed to write a perl program that can be run from the command line and connects up to the database but the user must pass in a username and password. I made the authentication pretty much exactly the same... -
grep an array for an element
I wrote this whilst other people replied but here it is anyway......probably a little verbose but it works :). You can make it better but I am too busy at the moment. #!/usr/bin/perl -w use strict; #make our variables my @a1 = qw/1 3 5 7 9 11 13/; my @a2 = qw/1 2 3 4 5 6 7/; my @new = ()... -
Converting perl statements to mod_perl statements
Hey, I have a mod_perl question. When the user clicks on a link I want them to be able to download a file. Below is the code I use to do it. It works fine. However, I want to make sure I am using mod_perl to it fullest, so I want to convert some of the statments to more mod_perlish (hope that... -
Syntactic Sugar and speed
Thanks for your input. Yeah, I didn't think there was any difference in speed or if any very miniscule. However, I like to program that way because I feel it is eaiser to read and debug, whereas some do not and I get the feeling that they feel it is bad programming or something....like doing a... -
Syntactic Sugar and speed
Do the various 'Syntactic Sugar' options slow down perl programs? ex: #$r is an apache request object $r->print("<form name=\"thisform\""); #vs. $r->print(qq@ <form name="thisform" @); I am just wondering because I find the qq makes complicated html print statements... -
reg expresion problem
Hey I think I may have solved my problem...not the way I wanted to do it...but hey it works. This is going back to what Paul said The thing was, I didn't want to set the | symbol to \| in my select box because I use it elsewhere. So in my map I just set a new variable to with the pipe...
