Name:seq_path - seq_file interface to print a pathname*@m: the seq_file handle*@path: the struct path to print*@esc: set of characters to escape in the output* return the absolute path of 'path', as represented by the* dentry / mnt pair in the path parameter.

Proto:int seq_path(struct seq_file *m, const struct path *path, const char *esc)

Type:int

Parameter:

TypeParameterName
struct seq_file *m
const struct path *path
const char *esc
467  size = seq_get_buf - get buffer to write arbitrary data to*@m: the seq_file handle*@bufp: the beginning of the buffer is stored here* Return the number of bytes available in the buffer, or zero if* there's no space.
