§ ldns_fget_token()

ssize_t ldns_fget_token ( FILE *  f,
char *  token,
const char *  delim,
size_t  limit 
)

returns a token/char from the stream F.

This function deals with ( and ) in the stream, and ignores them when encountered

Parameters
[in]*fthe file to read from
[out]*tokenthe read token is put here
[in]*delimchars at which the parsing should stop
[in]*limithow much to read. If 0 the builtin maximum is used
Returns
0 on error of EOF of the stream F. Otherwise return the length of what is read

§ ldns_fget_token_l()

ssize_t ldns_fget_token_l ( FILE *  f,
char *  token,
const char *  delim,
size_t  limit,
int *  line_nr 
)

returns a token/char from the stream F.

This function deals with ( and ) in the stream, and ignores when it finds them.

Parameters
[in]*fthe file to read from
[out]*tokenthe token is put here
[in]*delimchars at which the parsing should stop
[in]*limithow much to read. If 0 use builtin maximum
[in]line_nrpointer to an integer containing the current line number (for debugging purposes)
Returns
0 on error of EOF of F otherwise return the length of what is read

§ ldns_bget_token()

ssize_t ldns_bget_token ( ldns_buffer b,

size_t  limit 
)

returns a token/char from the buffer b.

This function deals with ( and ) in the buffer, and ignores when it finds them.

Parameters
[in]*bthe buffer to read from
[out]*tokenthe token is put here
[in]*delimchars at which the parsing should stop
[in]*limithow much to read. If 0 the builtin maximum is used
Returns
0 on error of EOF of b. Otherwise return the length of what is read
