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... |
|
fgetc(3) -- get next character or word from input stream
|
|
The fgetc() function obtains the next input character (if present) from the stream pointed at by stream, or the next character pushed back on the stream via ungetc(3). The getc() function acts essenti... |
|
fgetln(3) -- get a line from a stream
|
|
The fgetln() function returns a pointer to the next line from the stream referenced by stream. This line is not a C string as it does not end with a terminating NUL character. The length of the line, ... |
|
fgetpos(3) -- reposition a stream
|
|
The fseek() function sets the file position indicator for the stream pointed to by stream. The new position, measured in bytes, is obtained by adding offset bytes to the position specified by whence. ... |
|
fgets(3) -- get a line from a stream
|
|
The fgets() function reads at most one less than the number of characters specified by size from the given stream and stores them in the string str. Reading stops when a newline character is found, at... |
