apio	8fa72f3cf0	kernel+libc: Implement read()	2023-03-11 18:02:50 +01:00
apio	810c4bc257	kernel+libc: Start interfacing with the VFS from userspace (open & close) ... This commit adds open and close syscalls to the kernel, and adds matching wrappers to libc. No read/write support, so file descriptors are kind of useless for now.	2023-03-11 17:45:20 +01:00
apio	de38eb6877	luna: Remove pure_cstyle_format ... It was causing a lot of code duplication. If someone doesn't have errors, just return {} from the callback and unwrap the Result.	2023-03-02 13:38:21 +01:00
apio	03ed2c3e12	libc: Make dbgln() also print a newline in userspace ... Previously, dbgln() only printed a newline in kernel-space.	2023-02-25 17:36:03 +01:00
apio	7f8a8cdcaf	kernel, libc: Add an usleep() system call and use that to implement usleep() and sleep() in libc	2023-01-22 15:00:20 +01:00
apio	cb59a4e0e3	libc: Add assert.h	2023-01-22 12:51:30 +01:00
apio	a6974b605e	tools+CMake: Prefix all environment variables with LUNA_	2023-01-21 22:44:16 +01:00
apio	e3ef29e80d	libc: Implement wcstombs()	2023-01-14 11:59:08 +01:00
apio	00ee8314b3	luna: Make Utf8String{De,En}coders return the number of bytes written ... This means we can avoid a call to code_points() in mbstowcs(), which would parse a string twice.	2023-01-14 11:55:19 +01:00
apio	28bde216c4	libc: Implement perror()	2023-01-13 21:08:10 +01:00
apio	e676fb8299	libc: Add a wide range of time manipulation functions, including reentrant variants	2023-01-13 21:06:27 +01:00
apio	2d2db300b0	libc: Add malloc(), calloc(), realloc() and free()	2023-01-13 20:00:20 +01:00
apio	5fb2ff09c7	kernel, luna, libc: Move the heap code to a common zone, to be used by both kernel and userspace	2023-01-13 19:27:53 +01:00
apio	d864bda751	libc: Add (de)allocate_memory wrappers located in sys/mman.h	2023-01-13 19:08:02 +01:00
apio	586ca19b62	Add a VERY BASIC and hacky way of allocating memory from userspace ... Only supports one-page allocations and doesn't have libc wrappers, which means it has to be invoked using syscall().	2023-01-11 23:02:42 +01:00
apio	d150c55143	TarStream: Support mode	2023-01-11 18:42:50 +01:00
apio	c82ed5df01	Enable -Os on all targets	2023-01-10 18:13:21 +01:00
apio	a620b00b18	Unify libc header descriptions	2023-01-08 15:29:30 +01:00
apio	471103e4f3	Remove the word 'header' from libc header descriptions	2023-01-07 11:39:15 +01:00
apio	12dc96b4a5	Fix comment typo ... My bad :(	2023-01-07 11:31:08 +01:00
apio	b70bbc0ba6	More libc commenting	2023-01-07 11:21:53 +01:00
apio	7e377ef712	Implement printf()	2023-01-07 01:49:26 +01:00
apio	7fb2807d0c	libc: Implement time() using clock_gettime(). ... The cool POSIX kids use clock_gettime() now because it has NANOSECONDS (and different clocks!), but ANSI C prefers this function. We can still implement it based on clock_gettime(), we just have to discard the NANOSECONDS.	2023-01-07 00:27:23 +01:00
apio	a8a64863c8	kernel, libc: Add clock_gettime()	2023-01-07 00:21:08 +01:00

apio	8891304509	libc: Add ctype.h	2023-01-06 20:48:08 +01:00
apio	80f5c790f8	Implement string formatting into libc :) ... Of course, using <luna/Format.h> makes it so simple. No need for duplicate code!	2023-01-06 20:15:43 +01:00
apio	367a2ce521	libc: header documentation for supported functions	2023-01-06 20:02:07 +01:00

apio	bdfe7dac17	libc: Remove crti.o and crtn.o ... Looks like these are now provided by the compiler.	2023-01-06 17:59:54 +01:00
apio	8838e2cf22	Bring back the OS-Specific Toolchain on restart :^)	2023-01-06 17:35:07 +01:00
apio	7acef24494	Make libc depend on crt{0,i,n}.o	2023-01-06 14:32:38 +01:00
apio	129e3c434a	Switch to C for userspace, with a very bare-bones libc!!	2023-01-06 13:31:14 +01:00
