LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <linux/prctl.h>  /* Definition of PR_* constants */
       #include <sys/prctl.h>

       int prctl(PR_SET_FPEXC, unsigned long mode);

DESCRIPTION

       Set  floating-point  exception mode to mode.  Pass PR_FP_EXC_SW_ENABLE to use FPEXC for FP
       exception enables, PR_FP_EXC_DIV for floating-point  divide  by  zero,  PR_FP_EXC_OVF  for
       floating-point  overflow,  PR_FP_EXC_UND  for  floating-point underflow, PR_FP_EXC_RES for
       floating-point  inexact  result,  PR_FP_EXC_INV  for  floating-point  invalid   operation,
       PR_FP_EXC_DISABLED for FP exceptions disabled, PR_FP_EXC_NONRECOV for async nonrecoverable
       exception mode, PR_FP_EXC_ASYNC for async recoverable  exception  mode,  PR_FP_EXC_PRECISE
       for precise exception mode.

RETURN VALUE

       On  success,  0  is  returned.  On error, -1 is returned, and errno is set to indicate the
       error.
