INSTR(3) MBK UTILITY FUNCTIONS INSTR(3)
NAME
instr - find an occurence of a string in a string, starting at a specified character.
ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
Paris, France.
Web : http://asim.lip6.fr/recherche/alliance/
E-mail : alliance-users@asim.lip6.fr
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)
