It returns a non-zero (TRUE) 29integer if the strings are identical. 30 31The **curl_strnequal()** function is similar, except it only compares the 32first *length* characters of *str1*. 33 34These functions are provided by libcurl to enable applications to compare 35strings in a truly portable manner. There are no standard portable case 36insensitive string comparison functions. These two work on all platforms. 37 38# EXAMPLE 39 40~~~c 41int main(int argc, char **argv) 42{ 43 const char *name = "compare"; 44 if(curl_strequal(name, argv[1])) 45 printf("Name and input matches\n"); 46 if(curl_strnequal(name, argv[1], 5)) 47 printf("Name and input matches in the 5 first bytes\n"); 48} 49~~~ 50 51# AVAILABILITY 52 53Always 54 55# RETURN VALUE 56 57Non-zero if the strings are identical. Zero if they are not. 58
