Dear Board
I’m using STM32F103 controller, when I use strstr function for finding a word in a string the compiler throws a warning. No issue for me but the code works fine
But when I use strops(), the compiler throws error. It says this is used for C199 etc.. where can I see the string functions supported for MDK-IDE??
Below is the code im trying to execute for which IDE throws error
This code is extracted from keil reference book and applied for MDK according to my usage #include <string.h> #include <stdio.h> /* for printf */ void tst_strcat (void) { unsigned char buf [21]; unsigned char s [] = "Test String"; strcpy (buf, s); strcat (buf, " #2"); printf ("new string is %s\n", buf); }
sorry.. above copied code is incorrect..
please use the below mentioned code.
#include <string.h> #include <stdio.h> /* for printf */ void tst_strrpos (const char *s) { int i; i = strrpos (s, ' '); if (i == -1) printf ("No spaces found in %s\n", s); else printf ("Last space in %s is at offset %d\n", s, i); }
