Safe C string library

Introduction

String handling in standard C is an errorprone thing. To avoid this I implemented this little C string wrapper on top of the standard C string functions for a safe usage of strings. It is written in standard C. Instead of the cryptic naming of the standard C string functions proper names are used (see cstrings.h).

Features

• standard C strings as char*

• fast

• functions to set, concat, split, format, search strings

• safe in usage

Compile

Sorry, there is no makefile, but compilation is simple:

    
gcc -I. -c common/cstrings.c -D_GNU_SOURCE -DHAVE_LONG_LONG
gcc -I. -c common/lists.c -D_GNU_SOURCE
gcc -I. -c common/global.c -D_GNU_SOURCE
gcc -I. -c errors.c -D_GNU_SOURCE
gcc -I. -c cstrings_demo.c -D_GNU_SOURCE
gcc -o cstrings_demo cstrings_demo.o cstrings.o lists.o global.o errors.o

Please note:

• If no long long type is available, long long format cannot be done. Usually long long is checked in a configure script which set HAVE_LONG_LONG.

• Lists library is required for debug functions in strings and is included here, too.

License

String library is currently under GPL version 2.
