Hi every body,

I am migrating C code from HP-UX to LINUX RHEL5.
Minus sign flag for left justifying in printf doesn't work.

Could you have a look:

On the HP-UX side :

[gidtdev/oracle-gidtdev2]/users/devt/gidt/src/pc>uname -r
B.11.23
[gidtdev/oracle-gidtdev2]/users/devt/gidt/src/pc>uname
HP-UX
[gidtdev/oracle-gidtdev2]/users/devt/gidt/src/pc>more format.c
#include <string.h>
#include <stdio.h>

main( )
{

char chaine[ 5 ];

strcpy( chaine, "-----" );

printf( "|%10-s|\n", chaine );
printf( "lg=%d\n", strlen( chaine ) );

exit( 0 );
}
[gidtdev/oracle-gidtdev2]/users/devt/gidt/src/pc>cc format.c -o format
[gidtdev/oracle-gidtdev2]/users/devt/gidt/src/pc>format
|----- |
lg=5


----------On the LINUX REHL5 SIDE NOW

[gidtdevt.latelec.gl.local/gidt]/users/devt/gidt/src/pc>

{

char chaine[ 5 ];

strcpy( chaine, "-----" );

printf( "|%10-s|\n", chaine );
printf( "lg=%d\n", strlen( chaine ) );

exit( 0 );
}

[gidtdevt.latelec.gl.local/gidt]/users/devt/gidt/src/pc>

Can anybody help ?

I wish to avoid changing the code.

I hope it exists some compilation options.

The '-' is in the wrong place. Flags should come before the width. Try

printf( "|%-10s|\n", chaine );

I've always been taught that order of options as well, eg see: http://www.space.unibe.ch/comp_doc/c...NS/format.html
Maybe the HP compiler is smart enough (relaxed enough ?) to handle your original order...

Hi,

printf( "|%-10s|\n", chaine ); actually works!

Blimey! Something was for me more left justified in 10- than in -10... What a mistake!

I need to change all my code.

Thank you both of you ( Gazl and chrism01 ).

Have a nice day.

Alain.

In the future, could you enclose code examples in code blocks? Thanks.
