Info

_get_rmx_conn Translates a file descriptor to a valid iRMX connection token, usable as a parameter in iRMX system calls. _get_ss Returns an application’s current stack segment. _put_rmx_conn Places an iRMX connection token into the file descriptor table and returns a valid file descriptor, usable as an argument in C library calls. _set_info Modifies C library information. Low-level I/O Functions These functions provide low-level ways to manage file processing creat Creates a new file or opens an existing file for writing and truncates it to length 0, destroying the previous contents. eof Checks whether the file's current file pointer is EOF. lseek Moves the file pointer to a location specified as an offset from the origin in a file. ltell Sets the absolute position of the file pointer for the next I/O operation. open Opens a file and prepares it for subsequent reading or writing. read Reads the specified number of bytes from a file into a buffer, beginning at the current position of the file pointer. sopen Opens a file for shared reading or writing. write Writes data from a buffer to a file. Math Functions These functions provide such math functions as integer, floating point, trigonometric operations. abs Calculates the absolute value of an integer. acos Calculates the arccosine of a double value. asin Calculates the arcsine of a double value. atan Calculates the arctangent of a double value. atan2 Calculates the arctangent of the quotient of two doubles. Bessel functions Compute the Bessel function. cabs Calculates the absolute value of a complex number. 16 Chapter 2 Functional Groupings
ceil Calculates the ceiling (the smallest integer that is greater than or equal to the value) of a double value. cos Calculates the cosine. cosh Calculates the hyperbolic cosine of an angle. div Divides the numerator by the denominator, computing the quotient and the remainder of two integer values. exp Calculates the exponential of a double value. fabs Calculates the absolute value of a double value. floor Calculates the floor (largest integer that is less than or equal to a value) of a double value. fmod Calculates the floating-point remainder. frexp Gets the mantissa and exponent of a double value. labs Calculates the absolute value of a long integer. ldexp Computes a real number from the mantissa and exponent. ldiv Divides numerator by denominator, and computes the quotient and remainder. log Calculates the natural logarithm of a value. log10 Calculates the base-10 logarithm. matherr Processes errors generated by the functions of the math library. modf Splits a value into fractional and integer parts, retaining the sign. pow Computes a value raised to the power of another value. rand Generates a pseudo-random number. sin Calculates the sine. sinh Calculates the hyperbolic sine of an angle. sqrt Calculates the square root of a number. srand Sets the starting point for generating a series of pseudo-random integers. square Calculates the square of a number. tan Calculates the tangent. tanh Calculates the hyperbolic tangent of the number.
