C Coding Standards

When reviewing or generating C code, follow these rules:

File Naming

Source files: snake_case with
```
.c
```
extension (e.g.,
```
user_service.c
```
,
```
data_parser.c
```
)
Header files: snake_case with
```
.h
```
extension (e.g.,
```
user_service.h
```
,
```
data_parser.h
```
)
Keep names short but descriptive (max ~20 characters)

Header Guards

Format: UPPER_SNAKE_CASE with
```
_H
```
suffix
Include path in guard: (e.g.,
```
PROJECT_MODULE_FILE_H
```
)

#ifndef USER_SERVICE_H
#define USER_SERVICE_H
// content
#endif /* USER_SERVICE_H */

Variable Naming

Local variables: snake_case (e.g.,
```
user_count
```
,
```
buffer_size
```
,
```
is_valid
```
)
Global variables: snake_case with
```
g_
```
prefix (e.g.,
```
g_config
```
,
```
g_instance_count
```
)
Static variables: snake_case with
```
s_
```
prefix (e.g.,
```
s_initialized
```
,
```
s_cache
```
)
Pointers: Include
```
p
```
or
```
ptr
```
suffix when helpful (e.g.,
```
user_ptr
```
,
```
buffer_p
```
)

Constant/Macro Naming

Macros: UPPER_SNAKE_CASE (e.g.,
```
MAX_BUFFER_SIZE
```
,
```
DEFAULT_TIMEOUT
```
)
Enum values: UPPER_SNAKE_CASE (e.g.,
```
STATUS_OK
```
,
```
ERROR_INVALID_INPUT
```
)
Compile-time constants: UPPER_SNAKE_CASE with
```
#define
```

Function Naming

Functions: snake_case (e.g.,
```
calculate_total()
```
,
```
parse_input()
```
)
Module prefix: Use module name prefix (e.g.,
```
user_create()
```
,
```
user_destroy()
```
)
Static functions: snake_case, no prefix needed (internal to file)
Init/cleanup pairs: Use
```
_init()
```
and
```
_cleanup()
```
or
```
_create()
```
and
```
_destroy()
```

Type Naming

Structs: snake_case with
```
_t
```
suffix or PascalCase (e.g.,
```
user_data_t
```
or
```
UserData
```
)
Typedefs: snake_case with
```
_t
```
suffix (e.g.,
```
user_id_t
```
,
```
callback_fn_t
```
)
Enums: snake_case with
```
_e
```
suffix for type (e.g.,
```
status_e
```
)

Organization

Header includes at top (system headers, then project headers)
Macro definitions after includes
Type definitions (structs, enums, typedefs)
Function prototypes
Global/static variable declarations
Function implementations
