#include "sflstr.h" int istoken ( char **strLine, const char *strtoken, int *iWasToken)
Eats strToEat from strBuff only if it begins with contents of strToEat, and returns a 0 or 1 to tell what it did.
char strBuff[] = { "select * from mytbl;" }; int iWasToken; istoken (&strBuff, "SELECT", &iWasToken); On return here iWasToken would == 1, and strBuff would be: " * from mytbl;" If the token is not found, then strBuff will not be affected, and a 0 will be returned.
