Hello,

Can I read a file line by line???

lseek is to random access file, but I am interesting in read file line by line.

Best regards.

What language?

In many languages, including BASH, the command is "read".

Sorry, in a C programm.

Best regards

In your C library, isn't there something like stdio?

If I recall correctly, there's a lib function named "read"--or maybe "readline"

Never mind---this just in from Uncle Google:

You can use fgets() :

Code:

char * fgets (char *buffer, int max_size, FILE *file_to_read)

First argument points to a buffer you must provide. Second arg is the max line lenght to be read. Third is the file pointer to your file.

fgets returns a NULL pointer if it fails, otherwise it returns a pointer to the beginning of the buffer.

Finally, I do it with fgets.

Thanks a lot.
