Description

__FB_ERR__ indicates if -e, -ex, or -exx was specified on the compiler command line at the time of compilation of a module.

__FB_ERR__ indicates if -earray, -enullptr, or -elocation was specified on the compiler command line, or implied by use of -exx, at the time of compilation of a module.

__FB_ERR__ indicates if -edebug, -edebuginfo, or -eassert was specified on the compiler command line, or implied by use of -g, at the time of compilation of a module.

__FB_ERR__ indicates if -eunwind was specified on the compiler command line, or implied by use of -e, -ex, or -exx, at the time of compilation of a module.

__FB_ERR__ indicates if -earraydims was specified on the compiler command line, or implied by use of -exx, at the time of compilation of a module.

Returns bit-wise OR of the following values:

value	flag	description
0	no flag
1	errorcheck	implied by '-e', '-ex', '-exx'
2	resumeerr	implied by '-ex', '-exx'
4	extraerrchk	implied by '-exx'
8	arrayboundchk	implied by '-earray', '-exx'
16	nullptrchk	implied by '-enullptr', '-exx'
32	assertions	implied by '-eassert', '-g'
64	debuginfo	implied by '-edebuginfo', '-g'
128	debug	implied by '-edebug', '-g'
256	errlocation	implied by '-elocation', '-exx'
512	unwindinfo	implied by '-eunwind', '-e', '-ex', '-exx'
1024	arraydimscheck	implied by '-earraydims', '-exx'

__FB_ERR__ is always defined.
