mmap_read man page

mmap_read — memory map a file for reading


#include <mmap.h>

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


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.
