linux links

[nassim]

Could someone please point me in the right direction with regards to link 'files'. I would like to be able to use the linux c IO to find/query them, along with other data files. they seem to be evading the file radar: the readdir function (dirent.h) is not picking them.

On a different matter, my thanks to Derrick Coetzee for his sample 'pseudo code' fopen_mkdir. Dodgy as it may be, it was welcome help in my project. Here is my code for it:

#define FULLPERMISSIONS 0x41ff
 
FILE *fopen_mkdir( char *name, char *mode )
{
    char *mname = (char*) malloc( sizeof( char ) * MAXPATH );
    DIR *DIRp = 0;
    strcpy( mname, name );
    int len = 0, i;
    while ( mname[ len ] != '\0' ) {
         len++;
    }
    for( i = 0; i < len; i++ ) {
        if (( i > 0 ) && ( mname[ i ] == '/')) {
            mname[ i ] = '\0'; // read path up to a slash
            DIRp = opendir( mname );
            if(( mkdir( mname, FULLPERMISSIONS )) && ( !DIRp )) {
             // mkdir failed, NOT because dir already exists
                fprintf( stdout, " \n *** error opening %s *** \n", mname );
                return NULL;
            }
            if( DIRp ) {
                closedir( DIRp );
            }
            mname[ i ] = '/'; // put it back
        }
    }
    free( mname );
    return( fopen( name, mode));
}

Hi nassim, welcome to The Scripts.
Could you please better describe what you are trying to do? I am tying to figure out your end goal.
