vfs_is_dir
int vfs_is_dir(const char *path)
Checks if path is a file or a directory.
vfs_file_sha1
int vfs_file_sha1(const char *file, void *digest, void *work_buf, size_t work_buf_len)
Compute the SHA1 message digest of a file.
vfs_file_from_buffer
int vfs_file_from_buffer(const char *file, const void *buf, size_t len)
Writes the content of a buffer to a file If the file already exists, it will be overwritten.
vfs_file_exists
bool vfs_file_exists(const char *path)
Checks if path is a file and can be read.
vfs_file_to_buffer
int vfs_file_to_buffer(const char *file, void *buf, size_t len)
Reads the content of a file to a buffer.
vfs_file_sha256
int vfs_file_sha256(const char *file, void *digest, void *work_buf, size_t work_buf_len)
Compute the SHA256 message digest of a file.
vfs_unlink_recursive
int vfs_unlink_recursive(const char *root, char *path_buf, size_t max_size)
Behaves like rm -r @p root.
vfs_file_md5
int vfs_file_md5(const char *file, void *digest, void *work_buf, size_t work_buf_len)
Compute the MD5 message digest of a file.
