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 ...
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...
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...
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, ...
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. ...
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...
The fgetwc() function obtains the next input wide-character (if present) from the stream pointed at by stream, or the next character pushed back on the stream via ungetwc(3). The getwc() function acts...
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...
These functions are required or recommended by IEEE Std 754-1985. copysign() returns x with its sign changed to y's. finite() returns the value 1 just when -infinity < x < +infinity; otherwise a zero...

The fmtcheck function scans fmt_suspect and fmt_default to determine if fmt_suspect will consume the same argument types as fmt_default and to ensure that fmt_suspect is a valid format string. The pri...
