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]. |
|
atan2(3) -- arc tangent function of two variables
|
|
The atan2() and atan2f() functions compute the principal value of the arc tangent of y/x, using the signs of both arguments to determine the quadrant of the return value. |
|
atan2f(3) -- arc tangent function of two variables
|
|
The atan2() and atan2f() functions compute the principal value of the arc tangent of y/x, using the signs of both arguments to determine the quadrant of the return value. |
|
atanf(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]. |
|
atanh(3) -- inverse hyperbolic tangent function
|
|
The atanh() and atanhf() functions compute the inverse hyperbolic tangent of the real argument x. |
|
atanhf(3) -- inverse hyperbolic tangent function
|
|
The atanh() and atanhf() functions compute the inverse hyperbolic tangent of the real argument x. |
|
atexit(3) -- register a function to be called on exit
|
|
The atexit() function registers the given function to be called at program exit, whether via exit(3) or via return from the program's main. Functions so registered are called in reverse order; no arg... |
|
atof(3) -- convert ASCII string to double
|
|
The atof() function converts the initial portion of the string pointed to by nptr to double representation. It is equivalent to: strtod(nptr, (char **)NULL); |
|
atoi(3) -- convert ASCII string to integer
|
|
The atoi() function converts the initial portion of the string pointed to by nptr to integer representation. It is equivalent to: (int)strtol(nptr, (char **)NULL, 10); |
|
atol(3) -- convert ASCII string to long integer
|
|
The atol() function converts the initial portion of the string pointed to by nptr to long integer representation. It is equivalent to: strtol(nptr, (char **)NULL, 10); |
|
atoll(3) -- convert ASCII string to long long integer
|
|
The atoll() function converts the initial portion of the string pointed to by nptr to long long integer representation. It is equivalent to: strtoll(nptr, (char **)NULL, 10); |
