addr(3) -- Internet address manipulation routines
|
The routines inet_aton(), inet_addr() and inet_network() interpret character strings representing numbers expressed in the Internet standard `.' notation. The inet_pton() function converts a presenta... |
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... |
adler32(3) -- zlib general purpose compression library
|
This manual page describes the zlib general purpose compression library, version 1.1.4. The zlib compression library provides in-memory compression and decompression functions, including integrity che... |
alarm(3) -- set signal timer alarm
|
This interface is made obsolete by setitimer(2). The alarm() function waits a count of seconds before asserting the terminating signal SIGALRM. When the signal has successfully been caught, alarm() re... |
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 provides a high quality 32-bit pseudo-random number very quickly. arc4random() seeds itself on a regular basis from the kernel strong random number subsystem described in ran... |
arc4random_addrandom(3) -- arc4 random number generator
|
The arc4random() function provides a high quality 32-bit pseudo-random number very quickly. arc4random() seeds itself on a regular basis from the kernel strong random number subsystem described in ran... |
arc4random_stir(3) -- arc4 random number generator
|
The arc4random() function provides a high quality 32-bit pseudo-random number very quickly. arc4random() seeds itself on a regular basis from the kernel strong random number subsystem described in ran... |
asctime(3) -- convert date and time to ASCII
|
The ctime() function converts a time_t, pointed to by clock, representing the time in seconds since 00:00:00 UTC, 1970-01-01, and returns a pointer to a 26-character string of the form Thu Nov 24 18:2... |
asctime_r(3) -- convert date and time to ASCII
|
The ctime() function converts a time_t, pointed to by clock, representing the time in seconds since 00:00:00 UTC, 1970-01-01, and returns a pointer to a 26-character string of the form Thu Nov 24 18:2... |
asin(3) -- arc sine functions
|
The asin() function computes the principal value of the arc sine of x in the range [-pi/2, +pi/2]. The asinf() function is a single precision version of asin(). |
asinf(3) -- arc sine functions
|
The asin() function computes the principal value of the arc sine of x in the range [-pi/2, +pi/2]. The asinf() function is a single precision version of asin(). |
