strEQ is a C API for writing C extension for Perl. usage is straight
forward:
#!/usr/bin/perl -w
use strict;
use Inline 'C';
printf("'ab' and '12' is %s\n",
compareTwoString("ab","12") ? "same" : "different");
printf("'xx' and 'xx' is %s\n",
compareTwoString("xx","xx") ? "same" : "different");
__END__
__C__
bool compareTwoString(char* s1,char* s2){
bool r;
r = strEQ(s1,s2);
return r;
}
prints:
'ab' and '12' is different
'xx' and 'xx' is same
but if you are coding in Perl, you don't need to use this function. use
'eq','ne','cmp','gt','ge','le' and 'le' instead. i am almost certain that
you are looking at the wrong doc as a beginner. you should be looking at:
