man buffer_mmapread () - create read-only memory-mapped file buffer
NAME
buffer_mmapread - create read-only memory-mapped file buffer
SYNTAX
#include <buffer.h>
int buffer_mmapread(buffer &b,const char* filename);
DESCRIPTION
buffer_mmapread opens filename for reading and fills b so that the contents of the file can be read from it. Using mmap is more efficient than reading through a real buffer, but you have to call buffer_close to unmap the memory in the end.
EXAMPLE
#include <buffer.h> #include <open.h>
buffer input; char x;
buffer_mmapread(&input,"/etc/passwd"); while (buffer_get(&input,&x,1)==1) { buffer_put(buffer_1,&x,1); if (x=='\n') break; } buffer_flush(buffer_1); buffer_close(&input);
