/**
|
|
* 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 (argv[1] && streq(argv[1], "--verbose"))
|
|
* printf("verbose set\n");
|
|
* if (argv[1] && strstarts(argv[1], "--"))
|
|
* printf("Some option set\n");
|
|
* if (argv[1] && strends(argv[1], "cow-powers"))
|
|
* printf("Magic option set\n");
|
|
* return 0;
|
|
* }
