MMAP(2) OpenBSD Programmer's Manual MMAP(2) NAME mmap - map files or off_t offset); DESCRIPTION The mmap function causes the pages starting at addr andOn modern operating systems, it is possible to mmap (pronounced “em-map”) a file to a region of memory. When this is done, the file can be accessed just The mmap() function shall establish a mapping between a process' address space and a file, This manual page is part of the POSIX Programmer's Manual. The mmap() system call causes the pages starting at addr and continuing for at most len bytes to be mapped from the object described by fd, starting at byte The mmap () function causes the contents of fd , starting at offset , to be mapped in memory at the given addr . The mapping will extend at least len bytes, mmap allows you to directly map a file into the address space of your process without having to manually read it into memory sequentially. Typically this is mmap() creates a new mapping in the virtual address space of the calling process. The starting address for the new mapping is specified in addr. iOS Manual Pages · NAME · mmap -- map files or devices into memory · SYNOPSIS · #include · void * · mmap(void *addr, · len, int prot, int flags, int
