fpgetsticky(3)  IEEE FP mode control

A rounding mode is one of FP_RZ, FP_RM, FP_RN, or FP_RP, for rounding towards zero, rounding (Minus infinity) down, rounding to nearest, and rounding (Plus infinity) up. The default mode is FP_RN. An ... 
fprintf(3)  formatted output conversion

The printf() family of functions produces output according to a format as described below. printf() and vprintf() write output to stdout, the standard output stream; fprintf() and vfprintf() write out... 

fpsetmask(3)  IEEE FP mode control

A rounding mode is one of FP_RZ, FP_RM, FP_RN, or FP_RP, for rounding towards zero, rounding (Minus infinity) down, rounding to nearest, and rounding (Plus infinity) up. The default mode is FP_RN. An ... 
fpsetround(3)  IEEE FP mode control

A rounding mode is one of FP_RZ, FP_RM, FP_RN, or FP_RP, for rounding towards zero, rounding (Minus infinity) down, rounding to nearest, and rounding (Plus infinity) up. The default mode is FP_RN. An ... 
fpsetsticky(3)  IEEE FP mode control

A rounding mode is one of FP_RZ, FP_RM, FP_RN, or FP_RP, for rounding towards zero, rounding (Minus infinity) down, rounding to nearest, and rounding (Plus infinity) up. The default mode is FP_RN. An ... 
fpurge(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 ... 
fputc(3)  output a character or word to a stream

The fputc() function writes the character c (converted to an ``unsigned char'') to the output stream pointed to by stream. putc() acts essentially identically to fputc(), but is a macro that expands... 
fputs(3)  output a line to a stream

The function fputs() writes the string pointed to by str to the stream pointed to by stream. The function puts() writes the string str, and a terminating newline character, to the stream stdout. 
fputwc(3)  output a widecharacter to a stream

The fputwc() function writes the widecharacter wc to the output stream pointed to by stream. putwc() acts essentially identically to fputwc(), but is a macro that expands inline. It may evaluate str... 
fread(3)  binary stream input/output

The function fread() reads nmemb objects, each size bytes long, from the stream pointed to by stream, storing them at the location given by ptr. The function fwrite() writes nmemb objects, each size b... 
free(3)  general purpose memory allocation functions

The malloc() function allocates size bytes of memory. The allocated space is suitably aligned (after possible pointer coercion) for storage of any type of object. If the space is at least pagesize byt... 
freeaddrinfo(3)  nodenametoaddress translation

The getaddrinfo() function is defined for protocolindependent nodenametoaddress translation. It performs the functionality of gethostbyname(3) and getservbyname(3), but in a more sophisticated manne... 
freeifaddrs(3)  get interface addresses

The getifaddrs() function stores a reference to a linked list of the network interfaces on the local machine in the memory referenced by ifap. The list consists of ifaddrs structures, as defined in th... 
freopen(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... 
frexp(3)  convert floatingpoint number to fractional and integral components

The frexp() function breaks a floatingpoint number into a normalized fraction and an integral power of 2. It stores the integer in the int object pointed to by exp.
