NAME

ldns_bget_token, ldns_bgetc, ldns_bskipcs - get tokens from buffers

#include <stdint.h>
#include <stdbool.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. .br *b: the buffer to read from .br *token: the token is put here .br *delim: chars at which the parsing should stop .br *limit: how much to read. If 0 the builtin maximum is used .br 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(). .br *buffer: buffer to read from .br 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. .br *buffer: buffer to use .br *s: characters to skip .br Returns void
