bounds_checking_function

Description

• following the standard of C11 Annex K (bound-checking interfaces), functions of the common memory/string operation classes, such as memcpy_s, strcpy_s, are selected and implemented.

• other standard functions in C11 Annex K will be analyzed in the future and implemented in this organization if necessary.

• handles the release, update, and maintenance of bounds_checking_function.

Building

• compilation steps

1. Add all the .c files under /src to the source code listing for the build script.

2. In the build options, specify the header directory and the build options required for the project (for example, add
   -Ipath_to_include -fstack-protector-strong -fPIC -Wall -D_FORTIFY_SOURCE=2 -O2 in CFLAGS).

3. Generate .o files for each .c file.

4. Generate static or shared libraries for .o files according to project requirements.

• compiling examples:

  gcc -o memcpy_s.o -c -Iinclude -fstack-protector-strong -fPIC -Wall -D_FORTIFY_SOURCE=2 -O2 src/memcpy_s.c
