.SH NAME |
|
mmap_read \- memory map a file for reading |
|
.SH SYNTAX |
|
.B #include <libowfat/mmap.h> |
|
|
|
const char* \fBmmap_read\fP(const char* \fIfilename\fR,size_t* \fIfilesize\fR); |
|
.SH DESCRIPTION |
|
mmap_read opens \fIfilename\fR for reading, maps the whole file into |
|
memory, closes the file, writes the length of the file to \fIfilesize\fR |
|
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 \fBmunmap\fR from |
|
<sys/mman.h>. |
|
|
|
If the file could not be opened or mapped, (void*)0 is returned. |
