fclose(3) -- close a stream
|
|
The fclose() function dissociates the named stream from its underlying file or set of functions. If the stream was being used for output, any buffered data is written first, using fflush(3). |
|
fcvt(3) -- convert double to ASCII string
|
|
These functions are provided for compatibility with legacy code. New code should use the snprintf(3) function for improved safety and porta- bility. The ecvt(), fcvt() and gcvt() functions convert the... |
|
fdopen(3) -- stream open functions
|
|
The fopen() function opens the file whose name is the string pointed to by path and associates a stream with it. The argument mode points to a string beginning with one of the following sequences (add... |
|
FD_CLR(3) -- synchronous I/O multiplexing
|
|
select() examines the I/O descriptor sets whose addresses are passed in readfds, writefds, and exceptfds to see if some of their descriptors are ready for reading, are ready for writing, or have an ex... |
|
FD_ISSET(3) -- synchronous I/O multiplexing
|
|
select() examines the I/O descriptor sets whose addresses are passed in readfds, writefds, and exceptfds to see if some of their descriptors are ready for reading, are ready for writing, or have an ex... |
|
FD_SET(3) -- synchronous I/O multiplexing
|
|
select() examines the I/O descriptor sets whose addresses are passed in readfds, writefds, and exceptfds to see if some of their descriptors are ready for reading, are ready for writing, or have an ex... |
|
FD_ZERO(3) -- synchronous I/O multiplexing
|
|
select() examines the I/O descriptor sets whose addresses are passed in readfds, writefds, and exceptfds to see if some of their descriptors are ready for reading, are ready for writing, or have an ex... |
|
feof(3) -- check and reset stream status
|
|
The function clearerr() clears the end-of-file and error indicators for the stream pointed to by stream. The function feof() tests the end-of-file indicator for the stream pointed to by stream, return... |
|
ferror(3) -- check and reset stream status
|
|
The function clearerr() clears the end-of-file and error indicators for the stream pointed to by stream. The function feof() tests the end-of-file indicator for the stream pointed to by stream, return... |
|
fetch(3) -- database subroutines
|
|
These functions provide a dbm-compatible interface to the database access methods described in db(3). Each unique record in the database is a key/content pair, the components of which may be any arbit... |
|
fflagstostr(3) -- convert between file flag bits and their string names
|
|
The fflagstostr() function returns a comma separated string of the file flags represented by flags. If no flags are set a zero length string is returned. If memory cannot be allocated for the return v... |
|
fflush(3) -- flush a stream
|
|
The function fflush() forces a write of all buffered data for the given output or update stream via the stream's underlying write function. The open status of the stream is unaffected. If the stream ... |
|
ffs(3) -- find first bit set in a bit string
|
|
The ffs() function finds the first bit set in value and returns the index of that bit. Bits are numbered starting from 1, starting at the rightmost bit. A return value of 0 means that the argument was... |
