# [NAME](#NAME)

ldns\_bget\_token, ldns\_bgetc, ldns\_bskipcs - get tokens from buffers

# [SYNOPSIS](#SYNOPSIS)

#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);

# [DESCRIPTION](#DESCRIPTION)

*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
