hsearch(3) -- manage hash search table
|
|
The hcreate(), hdestroy() and hsearch() functions manage hash search tables. The hcreate() function allocates and initializes the table. The nel argument specifies an estimate of the maximum number of... |
|
hstrerror(3) -- get network host entry
|
|
The gethostbyname(), gethostbyname2() and gethostbyaddr() functions each return a pointer to an object with the following structure describing an internet host referenced by name or by address, respec... |

htonl(3) -- convert values between host and network byte order
|
|
These routines convert 16 and 32 bit quantities between network byte order and host byte order. The types in_addr_t and in_port_t are defined by X/Open as: typedef u_int32_t in_addr_t; typedef u_int16... |

hypot(3) -- euclidean distance and complex absolute value functions
|
|
The hypot() and cabs() functions computes the sqrt(x*x+y*y) in such a way that underflow will not happen, and overflow occurs only if the final result deserves it. hypot(infinity, v) = hypot(v, infini... |

hypotf(3) -- euclidean distance and complex absolute value functions
|
|
The hypot() and cabs() functions computes the sqrt(x*x+y*y) in such a way that underflow will not happen, and overflow occurs only if the final result deserves it. hypot(infinity, v) = hypot(v, infini... |

ieee(3) -- Functions for IEEE arithmetic
|
|
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... |
|
ieee_test(3) -- IEEE test functions
|
|
These functions allow users to test conformance to IEEE Std 754-1985. Their use is not otherwise recommended. logb(x) returns x's exponent n, a signed integer converted to double-precision floating-p... |
|
if_freenameindex(3) -- provide mappings between interface names and indexes
|
|
The if_nametoindex() function maps the interface name specified in ifname to its corresponding index. If the specified interface does not exist, it returns 0. The if_indextoname() function maps the in... |
|
if_indextoname(3) -- provide mappings between interface names and indexes
|
|
The if_nametoindex() function maps the interface name specified in ifname to its corresponding index. If the specified interface does not exist, it returns 0. The if_indextoname() function maps the in... |
|
if_nameindex(3) -- provide mappings between interface names and indexes
|
|

|
|
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... |
|
index(3) -- locate character in string
|
|
The index() function locates the first character matching c (converted to a char) in the null-terminated string s. |
