addr2ascii(3) -- Generic address formatting routines
|
|
The routines addr2ascii() and ascii2addr() are used to convert network addresses between binary form and a printable form appropriate to the address family. Both functions take an af argument, specify... |
|
addstr(3) -- add a string of characters to a curses window and advance cursor
|
|
These routines write the characters of the (null-terminated) character string str on the given window. It is similar to calling waddch once for each character in the string. The four routines with n a... |
|
alarm(3) -- set signal timer alarm
|
|
This interface is made obsolete by setitimer(2). The alarm() function sets a timer to deliver the signal SIGALRM to the calling process after the specified number of seconds. If an alarm has already b... |
|
alloca(3) -- memory allocator
|
|
The alloca() function allocates size bytes of space in the stack frame of the caller. This temporary space is automatically freed on return. |
|
alphasort(3) -- scan a directory
|
|
The scandir() function reads the directory dirname and builds an array of pointers to directory entries using malloc(3). It returns the number of entries in the array. A pointer to the array of direct... |
|
arc4random(3) -- arc4 random number generator
|
|
The arc4random() function uses the key stream generator employed by the arc4 cipher, which uses 8*8 8 bit S-Boxes. The S-Boxes can be in about (2**1700) states. The arc4random() function returns pseud... |
|
arc4random_addrandom(3) -- arc4 random number generator
|
|
The arc4random() function uses the key stream generator employed by the arc4 cipher, which uses 8*8 8 bit S-Boxes. The S-Boxes can be in about (2**1700) states. The arc4random() function returns pseud... |
|
arc4random_stir(3) -- arc4 random number generator
|
|
The arc4random() function uses the key stream generator employed by the arc4 cipher, which uses 8*8 8 bit S-Boxes. The S-Boxes can be in about (2**1700) states. The arc4random() function returns pseud... |
|
ascftime(3) -- convert date and time to string
|
|
The cftime() and ascftime() functions are made obsolete by strftime(3). Use of the functions cftime() and ascftime() is strongly deprecated, since there is no way to check for a buffer overflow condit... |
|
ascii2addr(3) -- Generic address formatting routines
|
|
The routines addr2ascii() and ascii2addr() are used to convert network addresses between binary form and a printable form appropriate to the address family. Both functions take an af argument, specify... |
|
asctime(3) -- transform binary date and time values
|
|
The functions ctime(), gmtime() and localtime() all take as an argument a time value representing the time in seconds since the Epoch (00:00:00 UTC, January 1, 1970; see time(3)). The function localti... |
|
asctime_r(3) -- transform binary date and time values
|
|
The functions ctime(), gmtime() and localtime() all take as an argument a time value representing the time in seconds since the Epoch (00:00:00 UTC, January 1, 1970; see time(3)). The function localti... |
|
asin(3) -- arc sine functions
|
|
The asin() and the asinf() functions compute the principal value of the arc sine of x. A domain error occurs for arguments not in the range [-1, +1]. For a discussion of error due to roundoff, see mat... |
