SYNOPSYS¶
#include "mut.h"
char ∗instr(s, find, from)
char ∗s, ∗find, from;
PARAMETERS¶
- s
- Pointer to the string to be searched for the pattern
- find
- Pointer to the string to be found, the pattern
- from
- Character to be searched backwards before searching for the pattern
DESCRIPTION¶
instr searches the first occurence of the string
find in the
string
s, starting its search at the last occurence of the
from
character in the string
s.
If either
s or
find is
NULL, the function returns
NULL. If
from is
(char)0, the pattern is searched from
the begining of
s.
This quite exotic behaviour is useful to search the occurence of a name in a
string resulting from a flatten, when only a terminal object name is to be
taken into account.
RETURN VALUES¶
instr return
NULL either if the pattern
find is not present
in the searched string
s, or if one at least of these two string are
NULL. If the pattern is found, a value different from
NULL is
returned.
EXAMPLE¶
#include "mut.h"
/* check for the pattern 'ck' anywhere in the string */
#define contains_ck(name) instr(name, "ck", ' ')
/* check for the pattern 'ck' in the signal name, not instance ones */
#define isclock(ptsig) instr(getsigname(ptsig), "ck", SEPAR)
