String comaprison

[samir singh]

Hi,

I am new to VxWorks and would like to know if there is any function for
string comparison without case or I have to write one.

Thanks in advance
Samir

The standard C functions, strcmp and strncmp are available
in most versions of vxWorks.

Speaking only for myself,

Yes, we have that but would like to have something which ignore case
while comparison like strcasecmp. Do you have any idea?

thanks
samir

HEELLLLOOOO! strncmp() What do you think it does? It isn't ANSI standard
though.

Bruce,
HEELLLLOOOO yourself. Maybe you should read the reference manual before
being so rude. strncmp() compares n bytes of a string and is case
sensitive. He is looking for something like stricmp() which is case
insensitve, but does not exist in VxWorks.

Samir,
I haven't found a case insenstive strcmp function in VxWorks.

strcasecmp isn't included in vxworks, but you can write your own
trivially. I think this is correct, haven't really tested it. Look
in the linux or *bsd sources (or P.J Plaugher's C library book) for
proven implementations.

int
strcasecmp(const char *s1, const char *s2) {
const char *t1 = (const char *)s1;
const char *t2 = (const char *)s2;

while (tolower(*t1) == tolower(*t2++))
if (*t1++ == '\0')
return (0);
return (tolower(*t1) - tolower(*--t2));
}
