The following sections are informative.
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);
...
None.
The creat() function is redundant. Its services are also provided by the open() function. It has been included primarily for historical purposes since many existing applications depend on it. It is best considered a part of the C binding rather than a function that should be provided in other languages.
None.
