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 "dotted quad" notation. The inet_pton() function converts... |
|
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 proccess seconds after the call to alarm(). If an alarm has already been... |
|
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... |

asctime(3) -- convert date and time to ASCII
|
|
ctime() converts a long integer, 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 18:22:48 19... |
|
asctime_r(3) -- convert date and time to ASCII
|
|
ctime() converts a long integer, 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 18:22:48 19... |
|
asin(3) -- arc sine function
|
|
The asin() and asinf() functions compute the principal value of the arc sine of x in the range [-pi/2, +pi/2]. |
|
asinf(3) -- arc sine function
|
|
The asin() and asinf() functions compute the principal value of the arc sine of x in the range [-pi/2, +pi/2]. |
|
asinh(3) -- inverse hyperbolic sine function
|
|
The asinh() and asinhf() functions compute the inverse hyperbolic sine of the real argument |
|
asinhf(3) -- inverse hyperbolic sine function
|
|
The asinh() and asinhf() functions compute the inverse hyperbolic sine of the real argument |
|
asprintf(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... |
|
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, consisting of the text of the expression, the name of the source file, the li... |
|
atan(3) -- arc tangent function of one variable
|
|
The atan() and atanf() functions compute the principal value of the arc tangent of x in the range [-pi/2, +pi/2]. |
