Re: Escape character treatment in string library functions


<rejithomas.d@xxxxxxxxx> wrote in message news:83c99c40-9b92-441a-ba95-f6536ed4759c@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Can I change the escape character used by string libraries?. My
requirement is to
parse a string in format "domain\username" and change it into domain\
\username.
The C library functions takes \ as an escape character and also treat
'\r' etc special making it difficult to parse even char by char.

Can anyone suggest any solution to this issue


char *doublebackslashes(char *in)
{
size_t count = 0;
size_t i = 0;
size_t j = 0;
char *answer = 0;

for(i=0;in[i];i++)
if(in[i] == '\\')
count++;
answer = malloc( strlen(in) + count + 1);
if(!answer)
return 0;
for(i=0;in[i];i++)
{
answer[j++] = in[i];
if(in[i] == '\\')
answer[j++] = '\\';
}
answer[j] = 0;

return answer;
}

int main(int argc, char **argv)
{
int i;

for(i=0;i<32;i++)
printf("%s\n", doublebackslashes("My\\Fred"));
return 0;
}

I've knocked up a little funcion for you.
I suspect that what you really need is a "make C escapes" however, which is a little more work.
