isfinite(3M)isfinite(3M)NAME
isfinite() - floating-point finiteness macro
SYNOPSIS
floating-type
DESCRIPTION
The macro determines whether its argument has a finite value (zero, denormalized, or normalized, and not infinite or NaN). The argument
must be of floating type, and classification is based on the type of the argument. For HP Integrity servers, the argument can be any
floating type. For PA-RISC, the argument must be either or
The macro implements the functionality recommended by the IEEE-754 standard for floating-point arithmetic.
USAGE
To use the macro, compile either with the default option or with the and options. Make sure your program includes Link in the math library
by specifying on the compiler or linker command line.
RETURN VALUE
The macro returns a nonzero value if and only if its argument has a finite value. The macro raises no floating-point exceptions.
ERRORS
No errors are defined.
EXAMPLES
Make sure a value is finite before continuing operations on it:
SEE ALSO fpclassify(3M), isinf(3M), isnan(3M), isnormal(3M), signbit(3M), math(5).
STANDARDS CONFORMANCE isfinite(3M)

I use Digital Unix 4.0F (OSF/1) .I write a simple programe :
#define _POSIX_SOURCE
#include <pthread.h>
void main(void)
{ }
But , the compiler report many errors .
I do not know why the compiler compain that .
Thank you in advance (1 Reply)
I'm upleveling code from 10.20 to 11.11....but I'm running into a problem in which the USRSTACK macro does not seem to be defined in 11.11. Has anybody else experienced this/fixed it/worked around it? Is there a different macro I should be using instead?
Thanks for any info you can provide!! (1 Reply)
I think there is no problem to use any macro in a new macro definishion, but I have a problem with that.
I can not understand why?
