This is the version of CCAN which CLN was using at the time these were taken. Unfortunately lots of whitespace has been changed, but AFAICT no source changes. Here's the command I ran (with ../ccan checked out to 1ae4c432): ``` make update-ccan CCAN_NEW="alignof array_size build_assert check_type container_of cppmagic likely list mem short_types str structeq take tal tal/str typesafe_cb utf8 endian crypto/sha256" ``` Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: William Casarin <jb55@jb55.com>

/**
|
|
* str - string helper routines
|
|
*
|
|
* This is a grab bag of functions for string operations, designed to enhance
|
|
* the standard string.h.
|
|
*
|
|
* Note that if you define CCAN_STR_DEBUG, you will get extra compile
|
|
* checks on common misuses of the following functions (they will now
|
|
* be out-of-line, so there is a runtime penalty!).
|
|
*
|
|
* strstr, strchr, strrchr:
|
|
* Return const char * if first argument is const (gcc only).
|
|
*
|
|
* isalnum, isalpha, isascii, isblank, iscntrl, isdigit, isgraph,
|
|
* islower, isprint, ispunct, isspace, isupper, isxdigit:
|
|
* Static and runtime check that input is EOF or an *unsigned*
|
|
* char, as per C standard (really!).
|
|
*
|
|
* Example:
|
|
* #include <stdio.h>
|
|
* #include <ccan/str/str.h>
|
|
*
|
|
* int main(int argc, char *argv[])
|
|
* {
|
|
* if (argc > 1 && streq(argv[1], "--verbose"))
|
|
* printf("verbose set\n");
|
|
* if (argc > 1 && strstarts(argv[1], "--"))
|
|
* printf("Some option set\n");
|
|
* if (argc > 1 && strends(argv[1], "cow-powers"))
|
|
* printf("Magic option set\n");
|
|
* return 0;
|
|
* }
