|
|
These functions operate on the group database file /etc/group which is described in group(5). Each line of the database is defined by the structure struct group found in the include file : stru... |
|
endhostent(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... |
|
|
endnetent(3) -- get network entry
|
|
The getnetent(), getnetbyname(), and getnetbyaddr() functions each return a pointer to an object with the following structure containing the broken-out fields of a line in the network database, /etc/n... |
|
endnetgrent(3) -- netgroup database operations
|
|
These functions operate on the netgroup database file /etc/netgroup.db which is described in netgroup(5). If that file does not exist, and the system supports YP, then the netgroup YP databases are us... |
|
endprotoent(3) -- get protocol entry
|
|
The getprotoent(), getprotobyname(), and getprotobynumber() functions each return a pointer to an object with the following structure containing the broken-out fields of a line in the network protocol... |
|
endpwent(3) -- password database operations
|
|
These functions operate on the password database file which is described in passwd(5). Each entry in the database is defined by the structure struct passwd found in the include file : struct pa... |
|
endrpcent(3) -- get RPC entry
|
|
getrpcent(), getrpcbyname(), and getrpcbynumber(), each return a pointer to an object with the following structure containing the broken-out fields of a line in the rpc program number database, /etc/r... |

endwin(3) -- curses screen initialization and manipulation routines
|
|
initscr is normally the first curses routine to call when initializing a program. A few special routines sometimes need to be called before it; these are slk_init, filter, ripoffline, use_env. For mul... |
|
erand48(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... |
|
erase(3) -- clear all or part of a curses window
|
|
The erase and werase routines copy blanks to every position in the window, clearing the screen. The clear and wclear routines are like erase and werase, but they also call clearok, so that the screen ... |
|
erasechar(3) -- curses environment query routines
|
|
The baudrate routine returns the output speed of the terminal. The number returned is in bits per second, for example 9600, and is an integer. The erasechar routine returns the user's current erase c... |
|
erf(3) -- error function operators
|
|
These functions calculate the error function of x. The erf() calculates the error function of x, and the erff() function is a single precision version of erf(). The error function is defined as: erf(x... |
