What is the difference between open() and fopen() in C language?
One is part of the standard c library (
fopen) so you can expect it to be present on all hosted c compiler setups. This function returns aFILE*which can be operated on by the functions in<stdio.h>.The other (
open) is a system call/function not specified by the c standard (however, i believe it is part of the POSIX standard) and therefore only guaranteed to exist on select platforms which claim to support it. This returns anintwhich represents a file, this can be operated on usingread/writeand other similar functions.
