.TH buffer_get_token_pred 3 |
|
.SH NAME |
|
buffer_get_token_pred \- read token from buffer |
|
.SH SYNTAX |
|
.B #include <buffer.h> |
|
|
|
ssize_t \fBbuffer_get_token_pred\fP(buffer* \fIb\fR,char* \fIx\fR,size_t \fIlen\fR, |
|
int (*\fIpredicate\fR)(const char* \fIs\fR,size_t \fIlen\fR)); |
|
.SH DESCRIPTION |
|
buffer_get_token_pred copies data from \fIb\fR to \fIx\fR[0], |
|
\fIx\fR[1], ..., \fIx\fR[\fIlen\fR-1] until \fIlen\fR bytes have been |
|
read or \fIpredicate\fR called on the destination string returns |
|
nonzero. |
|
|
|
\fIpredicate\fR can also return 0 (indicating further input is required |
|
to complete the token) or -1 (abort and return -1; use this if |
|
\fIpredicate\fR wants to enfore a maximum message size or does timeout |
|
handling or detects a malformed message). |
|
|
|
buffer_get_token_pred returns the number of bytes copied or -1 on |
|
error (setting \fIerrno\fR appropriately). |
