NAME

mmap_read - memory map a file for reading

SYNTAX

#include <libowfat/mmap.h>

const char* mmap_read (const char* filename ,size_t* filesize );

DESCRIPTION

mmap_read opens filename for reading, maps the whole file into memory, closes the file, writes the length of the file to filesize and returns a pointer to the mapped file.

The file is unmapped by the operating system if the process terminates. It can also be manually unmapped by calling munmap from <sys/mman.h>.

If the file could not be opened or mapped, (void*)0 is returned.
