- * strsplit - Split string into an array of substrings
- * @ctx: the context to tallocate from (often NULL)
- * @string: the string to split
- * @delims: delimiters where lines should be split.
- *
- * This function splits a single string into multiple strings. The
- * original string is untouched: an array is allocated (using talloc)
- * pointing to copies of each substring. Multiple delimiters result
- * in empty substrings. By definition, no delimiters will appear in
- * the substrings.
- *
- * The final char * in the array will be NULL, talloc_array_length() of the
- * returned value is 1 greater than the number of valid elements in
- * the array.
- *
- * Example:
- * #include <ccan/talloc/talloc.h>
- * #include <ccan/str_talloc/str_talloc.h>
- * ...
- * static unsigned int count_long_lines(const char *string)
- * {
- * char **lines;
- * unsigned int i, long_lines = 0;
- *
- * // Can only fail on out-of-memory.
- * lines = strsplit(NULL, string, "\n");
- * for (i = 0; lines[i] != NULL; i++)
- * if (strlen(lines[i]) > 80)
- * long_lines++;
- * talloc_free(lines);
- * return long_lines;
- * }

-/**
- * strjoin - Join an array of substrings into one long string
- * @ctx: the context to tallocate from (often NULL)
- * @strings: the NULL-terminated array of strings to join
- * @delim: the delimiter to insert between the strings
- *
- * This function joins an array of strings into a single string. The
- * return value is allocated using talloc. Each string in @strings is
- * followed by a copy of @delim.
- *
- * Example:
- * // Append the string "--EOL" to each line.
- * static char *append_to_all_lines(const char *string)
- * {
- * char **lines, *ret;
- *
- * lines = strsplit(NULL, string, "\n");
- * ret = strjoin(NULL, lines, "-- EOL\n");
- * talloc_free(lines);
- * return ret;

-/**
- * strreg - match and extract from a string via (extended) regular expressions.
- * @ctx: the context to tallocate from (often NULL)
- * @string: the string to try to match.
- * @regex: the regular expression to match.
- * ...: pointers to strings to allocate for subexpressions.
- *
- * Returns true if we matched, in which case any parenthesized
- * expressions in @regex are allocated and placed in the char **
- * arguments following @regex. NULL arguments mean the match is not
- * saved. The order of the strings is the order
- * of opening braces in the expression: in the case of repeated
- * expressions (eg "([a-z])*") the last one is saved, in the case of
- * non-existent matches (eg "([a-z]*)?") the pointer is set to NULL.
- *
- * Allocation failures or malformed regular expressions return false.
- *
- * See Also:
- * regcomp(3), regex(3).
- *
- * Example:
- * // Given 'My name is Rusty' outputs 'Hello Rusty!'
- * // Given 'my first name is Rusty Russell' outputs 'Hello Rusty Russell!'
- * // Given 'My name isnt Rusty Russell' outputs 'Hello there!'
- * int main(int argc, char *argv[])
- * {
- * char *person, *input;
- *
- * // Join args and trim trailing space.
- * input = strjoin(NULL, argv+1, " ");
- * if (strlen(input) != 0)
- * input[strlen(input)-1] = '\0';
- *
- * if (strreg(NULL, input, "[Mm]y (first )?name is ([A-Za-z ]+)",
- * NULL, &person))
- * printf("Hello %s!\n", person);
- * else
- * printf("Hello there!\n");
- * return 0;
