Define and use the unlink () function to delete a file. If successful, returns True, which returns false if it fails. The syntax unlink (filename,context) parameter describes the filename required. Specifies the files to be deleted. The context is

Each file can obtain the file information through a struct stat structure, where one member St_nlink the number of links representing the file.When using the shell's Touch command or open a nonexistent file with O_creat in the program, the number of

The function link, linkat, unlink, Unlinkat, and remove instance programs open a file and then unlink it. The process that executes the program then sleeps for 30 seconds and then terminates. #include "apue.h" #include int

Each file can obtain the file information through a struct stat struct. One of the member st_nlink represents the number of links to the file. Struct stat {unsigned longst_dev;/* device. */unsigned longst_ino;/* file serial number. */unsigned
