The result is the number of the signal that caused the childprocess to stop.The IPXFWSTOPSIG function should only be used if PXFWIFSTOPPED returns TRUE.See Also: “PXFWAIT”, “PXFWAITPID”, “PXFWIFSTOPPED”IPXFWTERMSIGPOSIX Function: Returns the number of the signal that caused a child process to terminate.Thisfunction is only available on Linux* systems.Module: USE IFPOSIXSyntaxresult = IPXFWTERMSIG (istat)istat(Input) INTEGER(4). The value of output argument istat from PXFWAIT or PXFWAITPID.Results:The result type is INTEGER(4). The result is the number of the signal that caused the childprocess to terminate.The IPXFWTERMSIG function should only be used if PXFWIFSIGNALED returns TRUE.See Also: “PXFWAIT”, “PXFWAITPID”, “PXFWIFSIGNALED”IRAND, IRANDMPortability Functions: Return random numbers in the range 0 through (2**31)–1, or 0 through(2**15)–1 if called without an argument.Module: USE IFPORTSyntaxresult = IRAND ([iflag])result = IRANDM (iflag)2-184
Descriptions of the Library Routines 2IRANGETiflag(Input) INTEGER(4). Optional for IRAND. Controls the way the returned random number ischosen. If iflag is omitted, it is assumed to be 0, and the return range is 0 through (2**15)–1(inclusive).Results:The result type is INTEGER(4). If iflag is 1, the generator is restarted and the first random value isreturned. If iflag is 0, the next random number in the sequence is returned. If iflag is neither zeronor 1, it is used as a new seed for the random number generator, and the functions return the firstnew random value.IRAND and IRANDM are equivalent and return the same random numbers. Both functions areincluded to ensure portability of existing code that references one or both of them.You can use SRAND to restart the pseudorandom number generator used by these functions.CompatibilityCONSOLE STANDARD GRAPHICS QUICKWIN GRAPHICS WINDOWS DLL LIBSee Also: “SRAND”, the RANDOM_NUMBER and RANDOM_SEED intrinsic routines in theLanguage ReferenceExampleUSE IFPORTINTEGER(4) istat, flag_value, r_nums(20)flag_value=1r_nums(1) = IRAND (flag_value)flag_value=0do istat=2,20r_nums(istat) = irand(flag_value)end doPortability Subroutine: Returns the current seed.Module: USE IFPORTSyntaxCALL IRANGET (seed)seed(Output) INTEGER(4).
