It returns a non-zero (TRUE) integer if 32the strings are identical. 33 34This function uses plain ASCII based comparisons completely disregarding the 35locale - contrary to how **strcasecmp** and other system case insensitive 36string comparisons usually work. 37 38This function is provided by libcurl to enable applications to compare strings 39in a truly portable manner. There are no standard portable case insensitive 40string comparison functions. This function works on all platforms. 41 42# %PROTOCOLS% 43 44# EXAMPLE 45 46~~~c 47int main(int argc, char **argv) 48{ 49 const char *name = "compare"; 50 if(curl_strequal(name, argv[1])) 51 printf("Name and input matches\n"); 52} 53~~~ 54 55# %AVAILABILITY% 56 57# RETURN VALUE 58 59Non-zero if the strings are identical. Zero if they are not. 60
