Limits on 32 and 64 bit in C++ / C

Hi All,

I am getting below run time error

I checked the code and see the structure defined as below and using the file position variable

typedef struct Get_file {
        char            *current_pathname;
        unsigned int    tot_bytes_io, physical_position;
        int file_position;
        int             remote;
        char            host[12];
        int             fd, open_mode;

the variable is a integer . I looked the binary and it was 32 bit compiled and the integer limit the output is saying is that. I did the compile in 64 bit. But I still see the issue . I am not sure why 64 bit compilation is not working

Thanks

This varies a bit among compilers, but in general, you get 64-bit types when you ask for them and otherwise are left with the same defaults as a 32-bit machine. Pointers of course become 64-bit on any architecture with a flat memory model.

Use size_t for sizes and positions, that's what it's there for. It will always be the right size of variable for whatever you're compiling on.

Hi.

To see arithmetic characteristics of compiler and machine, consider enquire:

Enquire: Everything you wanted to know about your C Compiler and Machine, but didn't know who to ask

Best wishes ... cheers, drl
