Chapter 8 - Environmental Control Functions / Controlling the Exception Flags

fegetexcept
You can use the fegetexcept function to save the current value of one or more floating-point exception flags.
void fegetexcept (fexcept_t *flagp, int excepts);
flagp
A pointer to where the exception flag values are to be stored.
excepts
A mask indicating which exception flags to save.

DESCRIPTION
The fegetexcept function saves the values of the floating-point exception flags specified by the argument excepts to the area pointed to by the argument flagp. The excepts argument may be one of the constants in Table 8-2 on page 8-6, two or more of these constants ORed together, or the constant FE_ALL_EXCEPT.

EXAMPLES
fegetexcept(flagp, FE_INVALID);     /* saves the invalid flag */
fegetexcept(flagp, FE_INVALID|FE_OVERFLOW|FE_DIVBYZERO);
      /* saves the invalid, overflow, and divide-by-zero flags */
fegetexcept(flagp, FE_ALL_EXCEPT);        /* saves all flags */
