NAME

SYNTAX

void buffer_init(buffer &b, ssize_t (*op)(int,char*,size_t), int fd, char* y, size_t ylen);

DESCRIPTION

buffer_init also prepares b to use the read/write operation specified by op and fd.

You can use

buffer b = BUFFER_INIT(op,fd,y,ylen);

to initialize b statically if op, fd, y, and ylen are compile-time constants.

You can call buffer_init again at any time. Note that this discards the currently buffered string.

EXAMPLE

char buf[4096]; int fd=open_read("/etc/services"); buffer input;

if (fd>=0) { char x; buffer_init(&input,read,fd,buf,sizeof buf); while (buffer_get(&input,&x,1)==1) { buffer_put(buffer_1,&x,1); if (x=='\n') break; } buffer_flush(buffer_1); }
