Table 3 shows functions that depend indirectly on one or more of the functions listed in Table 2. You can use Table 3 as an initial guide, but ARM recommends that you use either of the following to identify any other functions with indirect or direct dependencies on semihosting at link time:
asm(" .global __use_no_semihosting\n");in C source code.IMPORT __use_no_semihostingin armasm assembly language source code.
| Function | Usage |
|---|---|
__raise() | Catching, handling, or diagnosing C library exceptions, without C signal support. (Tailoring error signaling, error handling, and program exit.) |
__default_signal_handler() | Catching, handling, or diagnosing C library exceptions, with C signal support. (Tailoring error signaling, error handling, and program exit.) |
__Heap_Initialize() | Choosing or redefining memory allocation. Avoiding the heap and heap-using C library functions supplied by ARM. |
ferror(), fputc(), __stdout | Re-implementing the printf family. (Tailoring input/output functions in the C and C++ libraries.). |
__backspace(), fgetc(), __stdin | Re-implementing the scanf family. (Tailoring input/output functions in the C and C++ libraries.). |
fwrite(), fputs(), puts(),fread(), fgets(), gets(), ferror() | Re-implementing the stream output family. (Tailoring input/output functions in the C and C++ libraries.). |
