OSS Library Calls (e - f) fegetexceptflag(3)
NAME
fegetexceptflag - Gets floating-point exception flags
LIBRARY
H-series and J-series native Guardian processes: $SYSTEM.ZDLLnnn.ZCREDLL
32-bit H-series and J-series OSS processes: /G/system/zdllnnn/zcredll
64-bit H-series and J-series OSS processes: /G/system/zdllnnn/ycredll
SYNOPSIS
#include <fenv.h>
int fegetexceptflag(
fexcept_t *flagp,
int excepts);
PARAMETERS
flagp Specifies the object that is to store the floating-point exception flags.
excepts Specifies the floating-point exception flags that are to be obtained.
DESCRIPTION
The fegetexceptflag( ) function stores a representation of the states of the floating-point excep-
tion flags indicated by the parameter excepts in the object pointed to by the parameter flagp.
The parameter excepts can be constructed as a bitwise OR of the exception macros:
FE_INEXACT, FE_DIVBYZERO, FE_UNDERFLOW, FE_OVERFLOW, and
FE_INVALID. FE_ALL_EXCEPT represents all the floating-point exceptions.
NOTES
This function is implemented only for the IEEE_float floating-point option. Applications using
this function cannot be compiled if the specified floating-point option is Tandem_float.
RETURN VALUES
The fegetexceptflag( ) function always returns 0 (zero), indicating that a representation was suc-
cessfully stored.
RELATED INFORMATION
