eatstr

SFL
Version 2.11

`eatstr`

#include "sflstr.h"
char *
eatstr (
    char **strBuff,
    char *strToEat)

Synopsis

Eats strToEat from strBuff only if it begins with contents of strToEat.

Examples

       char strBuff[] = { "select * from mytbl;" };
       eatstr (&strBuff, "SELECT");

       On return here strBuff would be: " * from mytbl;"

    If the token is not found, then strBuff will not be affected and
    a NULL char * will be returned, but any white spaces on the left
    of strBuff would be trimed.
