Detailed Description

Header file for C runtime initialization and system functions.

This header file provides declarations for functions and structures used during the C runtime initialization process and other system-level operations. These functions and structures are typically reserved for system use and should not be called directly by user applications.

Function Documentation

_ioctl()

int _ioctl ( int fd, unsigned int cmd, void * arg )

extern

Performs an IOCTL operation on a file.

This function performs an IOCTL operation on the specified file descriptor with the given command and argument.

Parameters

fd	The file descriptor.
cmd	The IOCTL command.
arg	The argument for the IOCTL command.

Returns

int 0 on success, negative value on failure.

fs_register_driver()

int fs_register_driver ( const char * path, const file_operations * fops, mode_t mode, void * priv )

extern

Registers a file system driver.

This function registers a new file system driver with the specified path, file operations, access mode, and private data.

Parameters

path	The path managed by the driver.
fops	The file operations supported by the driver.
mode	The access mode for the driver.
priv	The driver-specific private data.

Returns

int 0 on success, negative value on failure.
