NAME
fetestexcept() - test floating-point exceptions
SYNOPSIS
DESCRIPTION
The function determines which of a specified subset of the floating-point exception flags are currently set. The excepts argument speci-
fies the floating-point exception flags to be queried. The argument can be constructed as a bitwise OR of the exception macros: and repre-
sents all the floating-point exceptions.
USAGE
To use this function, compile either with the default option or with the and options. Make sure your program includes
For HP Integrity servers, specify on the compiler command line or place the call to this function under the effect of an affirmative
pragma:
If the pragma is placed outside of any top-level declarations in a file, the pragma will apply to all declarations in the compilation fol-
lowing the pragma until another pragma is encountered or until the end of the file is reached.
If the pragma is placed at the beginning of a block (compound statement), the pragma will apply until another pragma is encountered or
until the end of the block is reached.
For PA-RISC, you might need to use the compiler option in order to prevent optimizations that can undermine the specified behavior of this
function.
Link in the math library by specifying on the compiler or linker command line.
