Due to the complexity that writing some code that expects a string input from the user, I've made this tiny library which can be used in any case (e.g.: the programmer doesn't need to worry anymore of how many characters/bytes the user must give, neither the boring details of handling NULL or memory allocation).
With these functions, you should only expect some string (any size) or nothing, that simple.
obs. 2: if you are interested in another tool for string manipulation, check the following repository. It's about extracting a slice from a given String.
obs. 3: wanna check out a variadic version (more flexible way of giving args) of this function? Click on the link bellow that goes to another repository
Using this library requires nothing more than moving the source-code at src/ into your project diretory that hold your .c files.
Finally, just the obvious, use GCC to compile all the code inside :
gcc *.c -o [executable_name]
Execute with (if you are in a Windows OS, use a backslash instead):
./[executable_name]
| Function | Parameter | Return |
|---|---|---|
| read | String literal to be printed before your reading process, null to print nothing | String with user input |
| clean | String reference | Nothing |
If you want to take an example, check the code inside test/, at main.c.
"read( )" expects some hardcoded string to be passed, which will serve as some sort of label. For example
printf("Say your name: \n");
char* yourName = read(" >>> ");
Will be printed as follows:
$ Say your name:
$ >>> Kimi no na wa
If you don't want any message, just pass as null:
printf("Say your name: \n");
char* yourName = read(NULL);
$ Say your name:
$ Kimi no na wa
"clean( )" only expects a dynamically-allocated string to be freed. If null is passed, nothing will happen.
