ldns(3) Library Functions Manual ldns(3)


ldns_bget_token, ldns_bgetc, ldns_bskipcs - get tokens from buffers


#include <stdint.h>
#include <stdbool.h>

#include <ldns/ldns.h>

ssize_t ldns_bget_token(ldns_buffer *b, char *token, const char *delim, size_t limit);

int ldns_bgetc(ldns_buffer *buffer);

void ldns_bskipcs(ldns_buffer *buffer, const char *s);


ldns_bget_token() returns a token/char from the buffer b. This function deals with ( and ) in the buffer, and ignores when it finds them.
*b: the buffer to read from
*token: the token is put here
*delim: chars at which the parsing should stop
*limit: how much to read. If 0 the builtin maximum is used
Returns s 0 on error of EOF of b. Otherwise return the length of what is read

ldns_bgetc() returns the next character from a buffer. Advances the position pointer with 1. When end of buffer is reached returns EOF. This is the buffer's equivalent for getc().
*buffer: buffer to read from
Returns EOF on failure otherwise return the character

ldns_bskipcs() skips all of the characters in the given string in the buffer, moving the position to the first character that is not in *s.
*buffer: buffer to use
*s: characters to skip
Returns void
