Example 1 Creating a File
The following example creates the file /tmp/file with read and write permissions for the file owner and read permission for group and others. The resulting file descriptor is assigned to the fd variable.
#include <fcntl.h> ... int fd; mode_t mode = S_IRUSR | S_IWUSR | S_IRGRP | S_IROTH; char *filename = "/tmp/file"; ... fd = creat(filename, mode); ...
The creat() function has a transitional interface for 64-bit file offsets. See lf64(7).
