Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

# NAME
|
|
|
|
curl_strequal, curl_strnequal - case insensitive string comparisons
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
int curl_strequal(const char *str1, const char *str2);
|
|
int curl_strnequal(const char *str1, const char *str2, size_t length);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
The curl_strequal(3) function compares the two strings *str1* and
|
|
*str2*, ignoring the case of the characters. It returns a non-zero (TRUE)
|
|
integer if the strings are identical.
|
|
|
|
The **curl_strnequal()** function is similar, except it only compares the
|
|
first *length* characters of *str1*.
|
|
|
|
These functions are provided by libcurl to enable applications to compare
|
|
strings in a truly portable manner. There are no standard portable case
|
|
insensitive string comparison functions. These two work on all platforms.
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
int main(int argc, char **argv)
|
|
{
|
|
const char *name = "compare";
|
|
if(curl_strequal(name, argv[1]))
|
|
printf("Name and input matches\n");
|
|
if(curl_strnequal(name, argv[1], 5))
|
|
printf("Name and input matches in the 5 first bytes\n");
|
|
}

|
|
|
|
# RETURN VALUE
|
|
|
|
Non-zero if the strings are identical. Zero if they are not.
