NAME

       fegetenv() - get floating-point environment

SYNOPSIS

   HP Integrity Server Only
   PA-RISC Only
DESCRIPTION

       The function stores the current floating-point environment in the object pointed to by the argument envp.

       To use this function, compile either with the default option or with the and options.

       Make sure your program includes

       For 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 +Onomoveflops 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.
