NAME
fegettrapenable() - get floating-point exception trap enables SYNOPSIS
DESCRIPTION
The function determines which floating-point exception traps are currently 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 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. For more information, see the at the following site: 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
No errors are defined. EXAMPLES
Retrieve the current trap settings and determine whether a trap for the divide by zero exception is enabled. AUTHOR
