curldown is this new file format for libcurl man pages. It is markdown inspired with differences: - Each file has a set of leading headers with meta-data - Supports a small subset of markdown - Uses .md file extensions for editors/IDE/GitHub to treat them nicely - Generates man pages very similar to the previous ones - Generates man pages that still convert nicely to HTML on the website - Detects and highlights mentions of curl symbols automatically (when their man page section is specified) tools: - cd2nroff: converts from curldown to nroff man page - nroff2cd: convert an (old) nroff man page to curldown - cdall: convert many nroff pages to curldown versions - cd2cd: verifies and updates a curldown to latest curldown This setup generates .3 versions of all the curldown versions at build time. CI: Since the documentation is now technically markdown in the eyes of many things, the CI runs many more tests and checks on this documentation, including proselint, link checkers and tests that make sure we capitalize the first letter after a period... Closes #12730

# 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");
|
|
}
|

# AVAILABILITY

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