strings

[Kohinoor24]

Hi,

I have a string like this as follows:

const char* Text = "CZARIUC=CHS,IND,e:\tools\rs\300\test,"

I want to take the string part,which is coming before The "=" Sign.ie: only CZARIUC.

How Can I do that?

Thanks in Advance..

MSDN:

strtok, wcstok
Find the next token in a string.

Routine Required Header
strtok <string.h>
wcstok <string.h>


char *strtok( char *strToken, const char *strDelimit );
wchar_t *wcstok( wchar_t *strToken, const wchar_t *strDelimit );
Parameters
strToken
String containing token(s)
strDelimit
Set of delimiter characters
Libraries
All versions of the C run-time libraries.

Return Value
All of these functions return a pointer to the next token found in strToken. They return NULL when no more tokens are found. Each call modifies strToken by substituting a NULL character for each delimiter that is encountered.

Remarks
The strtok function finds the next token in strToken. The set of characters in strDelimit specifies possible delimiters of the token to be found in strToken on the current call. wcstok is the wide-character version of strtok. The arguments and return value of wcstok are wide-character strings. These two functions behave identically otherwise.

Generic-Text Routine Mappings
TCHAR.H Routine _UNICODE Defined
_tcstok wcstok


On the first call to strtok, the function skips leading delimiters and returns a pointer to the first token in strToken, terminating the token with a null character. More tokens can be broken out of the remainder of strToken by a series of calls to strtok. Each call to strtok modifies strToken by inserting a null character after the token returned by that call. To read the next token from strToken, call strtok with a NULL value for the strToken argument. The NULL strToken argument causes strtok to search for the next token in the modified strToken. The strDelimit argument can take any value from one call to the next so that the set of delimiters may vary.

Warning Each of these functions uses a static variable for parsing the string into tokens. If multiple or simultaneous calls are made to the same function, a high potential for data corruption and inaccurate results exists. Therefore, do not attempt to call the same function simultaneously for different strings and be aware of calling one of these functions from within a loop where another routine may be called that uses the same function. However, calling this function simultaneously from multiple threads does not have undesirable effects.

Example
/* STRTOK.C: In this program, a loop uses strtok
* to print all the tokens (separated by commas
* or blanks) in the string named "string".
*/

#include <string.h>
#include <stdio.h>

char string[] = "A string\tof ,,tokens\nand some more tokens";
char seps[] = " ,\t\n";
char *token;

void main( void )
{
printf( "%s\n\nTokens:\n", string );
/* Establish string and get the first token: */
token = strtok( string, seps );
while( token != NULL )
{
/* While there are tokens in "string" */
printf( " %s\n", token );
/* Get next token: */
token = strtok( NULL, seps );
}
}

Output
A string of ,,tokens
and some more tokens

Tokens:
A
string
of
tokens
and
some
more
tokens

I hope this is a typo

const char* Text = "CZARIUC=CHS,IND,e:\tools\rs\300\test,"

It should be

const char* Text = "CZARIUC=CHS,IND,e:\\tools\\rs\\300\\test,"

otherwise \t translates to tab and \r translates to return.
