|
The secure_path() function takes a path name and returns zero if the referenced file is ``secure'', non-zero if not. Any ``insecurity'', other than failure to access the referenced file, will be l... |
|
seed48(3) -- pseudo random number generators and initialization routines
|
|
The rand48() family of functions generates pseudo-random numbers using a linear congruential algorithm working on integers 48 bits in size. The particular formula employed is r(n+1) = (a * r(n) + c) m... |
|
seekdir(3) -- directory operations
|
|
The opendir() function opens the directory named by filename, associates a directory stream with it and returns a pointer to be used to identify the directory stream in subsequent operations. The poin... |

The getdiskbyname() function takes a disk name (e.g. `rm03') and returns a prototype disk label describing its geometry information and the standard disk partition tables. All information is obtained... |
|
setdomainname(3) -- get/set domain name of current host
|
|
getdomainname() returns the standard domain name for the current processor, as previously set by setdomainname(). The parameter namelen specifies the size of the name array. The returned name is null-... |
|
setenv(3) -- environment variable functions
|
|
These functions set, unset and fetch environment variables from the host environment list. For compatibility with differing environment conventions, the given arguments name and value may be appended ... |
|
setfsent(3) -- get file system descriptor file entry
|
|
The getfsent(), getfsspec(), and getfsfile() functions each return a pointer to an object with the following structure containing the brokenout fields of a line in the file system description file, |
|
setgrent(3) -- group database operations
|
|
These functions operate on the group database file which is described in group(5). Each line of the database is defined by the structure group found in the include file : struct group { char *g... |
|
setgroupent(3) -- group database operations
|
|
These functions operate on the group database file which is described in group(5). Each line of the database is defined by the structure group found in the include file : struct group { char *g... |
|
sethostent(3) -- get network host entry
|
|
The gethostbyname(), gethostbyname2() and gethostbyaddr() functions each return a pointer to an object with the following structure describing an internet host referenced by name or by address, respec... |
