fmod(3) -- floating-point remainder function
|
|
The fmod() function computes the remainder of dividing x by y. The return value is x - n * y, where n is the quotient of x / y, rounded towards zero to an integer. |
|
fnmatch(3) -- match filename or pathname
|
|
The fnmatch() function checks whether the string argument matches the pattern argument, which is a shell wildcard pattern. The flags argument modifies the behaviour; it is the bitwise OR of zero or mo... |

|
fopen(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 (Addit... |
|
fpathconf(3) -- get configuration values for files
|
|
fpathconf() gets a value for the configuration option name for the open file descriptor filedes. pathconf() gets a value for configuration option name for the file name path. The corresponding macros ... |
|
fputwc(3) -- write a wide character to a FILE stream
|
|
The fputwc function is the wide-character equivalent of the fputc function. It writes the wide character wc to stream. If ferror(stream) becomes true, it returns WEOF. If a wide character conversion e... |
|
fputws(3) -- write a wide character string to a FILE stream
|
|
The fputws function is the wide-character equivalent of the fputs function. It writes the wide character string starting at ws, up to but not including the terminating L'\0' character, to stream. |
|
fread(3) -- binary stream input/output
|
|
The function fread reads nmemb elements of data, each size bytes long, from the stream pointed to by stream, storing them at the location given by ptr. The function fwrite writes nmemb elements of dat... |
|
frexp(3) -- convert floating-point number to fractional and integral components
|
|
The frexp() function is used to split the number x into a normalized fraction and an exponent which is stored in exp. |
|
fseek(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. If... |
|
ftime(3) -- return date and time
|
|
Return current date and time in tp, which is declared as following: struct timeb { time_t time; unsigned short millitm; short timezone; short dstflag; }; The structure contains the time since the epoc... |
|
ftok(3) -- convert a pathname and a project identifier to a System V IPC key
|
|
The function converts the pathname of an existing accessible file and a project identifier into a key_t type System V IPC key. |
|
fts(3) -- traverse a file hierarchy
|
|
The fts functions are provided for traversing UNIX file hierarchies. A simple overview is that the fts_open() function returns a ``handle'' on a file hierarchy, which is then supplied to the other f... |
|
ftw(3) -- file tree walk
|
|
ftw() walks through the directory tree starting from the indicated directory dir. For each found entry in the tree, it calls fn() with the full pathname of the entry, a pointer to the stat(2) structur... |
|
fwide(3) -- set and determine the orientation of a FILE stream
|
|
When mode is zero, the fwide function determines the current orientation of stream. It returns a value > 0 if stream is wide-character oriented, i.e. if wide character I/O is permitted but char I/O is... |
|
gcvt(3) -- convert a floating-point number to a string.
|
|
The gcvt() function converts number to a minimal length NULL terminated ASCII string and stores the result in buf. It produces ndigit significant digits in either printf(3) F format or E format. |
