Name:mangle_path - mangle and copy path to buffer beginning*@s: buffer start*@p: beginning of path in above buffer*@esc: set of characters that need escaping* Copy the path from @p to @s, replacing each occurrence of character from*@esc with usual octal escape

Proto:char *mangle_path(char *s, const char *p, const char *esc)

Type:char

Parameter:

TypeParameterName
char *s
const char *p
const char *esc
436  When s <= p cycle
437  c = p++
438  If Not c Then
439  Return s
440  Else if Not strchr - Find the first occurrence of the character c in the string s.*@s: the string to be searched*@c: the character to search for Then
441  s++ = c
442  Else if s + 4 > p Then
443  Break
444  Else
445  s++ = '\\'
446  s++ = '0' + ((c & 0300) >> 6)
447  s++ = '0' + ((c & 070) >> 3)

seq_pathseq_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.
seq_path_rootSame as seq_path, but relative to supplied root.
