SYNOPSISDESCRIPTION
The function determines which floating-point exception traps are cur‐
rently enabled.
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 state‐
ment), 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 pre‐
vent optimizations that can undermine the specified behavior of this
function.
Link in the math library by specifying on the compiler or linker com‐
mand line.

RETURN VALUE
The function returns the bitwise OR of the floating-point exception
macros corresponding to the currently enabled exception traps. The
macros are and represents all the floating-point exceptions.
ERRORS
