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(). |
|
asinh(3) -- inverse hyperbolic sine functions
|
|
The asinh() function computes the inverse hyperbolic sine of the real argument. The asinhf() function is a single precision version of asinh(). |
|
asinhf(3) -- inverse hyperbolic sine functions
|
|
The asinh() function computes the inverse hyperbolic sine of the real argument. The asinhf() function is a single precision version of asinh(). |
|
asprintf(3) -- formatted output conversion
|
|
The printf() family of functions produce output according to the given format as described below. This format may contain ``conversion specifiers''; the results of such conversions, if any, depend o... |
|
assert(3) -- expression verification macro
|
|
The assert() macro tests the given expression and if it is false, the calling process is terminated. A diagnostic message is written to stderr and the abort(3) function is called, effectively terminat... |
