1) Attempts to obtain the full contents of the floating-point exception flags that are listed in the bitmask argument
excepts
, which is a bitwise OR of the
floating point exception macros
.
2) Attempts to copy the full contents of the floating-point exception flags that are listed in
excepts
from
flagp
into the floating-point environment. Does not raise any exceptions, only modifies the flags.
The full contents of a floating-point exception flag is not necessarily a boolean value indicating whether the exception is raised or cleared. For example, it may be a struct which includes the boolean status and the address of the code that triggered the exception. These functions obtain all such content and obtain/store it in
flagp
in implementation-defined format.
Parameters
| flagp | - | pointer to an std:: fexcept_t object where the flags will be stored or read from |
| excepts | - | bitmask listing the exception flags to get/set |
Return value
0 on success, non-zero otherwise.
