Hi,

I made this function which should to log theLinks into
theLogFile, and return -1 if there was a problem, 0 if
theLinks has just been logged, or 1 if it was logged
before.
The problem is that somehow sometimes it cannot open
theFile even though theLogFile exits at the market
line.
Does anyone have any idea about the problem?
I'm using gcc on a Linux box if it matters.

Thanks a lot,

Andre


# include "logf.h"

int logLink( const char * theLink, const char *
theLogFile )
{
	char theLine[ 256 ];
	FILE * theFile;

	bzero( theLine, 256 );

	theFile = fopen( theLogFile, "r+" );
	if( theFile == NULL )
	{
		theFile = fopen( theLogFile, "w" );
		if( theFile == NULL )
It exits here-> return( -1 );
	}

	while( fgets( theLine, 256, theFile ) )
	{
		if( strcmp( theLine, theLink ) == 0 )
		{
			fclose( theFile );
			return( 1 );
		}
	}

	if( fprintf( theFile, "%s", theLink ) < 0 )
	{
		fclose( theFile );
		return( -1 );
	}
	fclose( theFile );

	return( 0 );
}
