Operating system specific routines.

Placed here to avoid cluttering up code with OS files.

Compiler implementation of the D programming language.

Functions

file_8dot3name char* file_8dot3name(char* filename): For 16 bit programs, we need the 16 bit filename.
file_createdirs int file_createdirs(char* name): Create directories up to filename. Input: name path/filename
file_write int file_write(char* name, void* buffer, uint len): Write a file.
os_clock int os_clock()
os_critsecsize32 int os_critsecsize32(): Return size of OS critical section. NOTE: can't use the sizeof() calls directly since cross compiling is supported and would end up using the host sizes rather than the target sizes.
os_critsecsize64 int os_critsecsize64(): Return size of OS critical section. NOTE: can't use the sizeof() calls directly since cross compiling is supported and would end up using the host sizes rather than the target sizes.
os_error void os_error(int line): Called when there is an error returned by the operating system. This function does not return.
os_file_exists int os_file_exists(char* name): Return !=0 if file exists. 0: file doesn't exist 1: normal file 2: directory
os_freelibrary void os_freelibrary()
os_getprocaddress void* os_getprocaddress(char* funcname)
os_heapinit void os_heapinit(): Do our own storage allocator (being suspicious of the library one).
os_heapterm void os_heapterm(): Do our own storage allocator (being suspicious of the library one).
os_term void os_term()
os_unique uint os_unique(): ///////////////////////////////////////
vmem_baseaddr void* vmem_baseaddr(): Determine a base address that we can use for mapping files to.
vmem_commit int vmem_commit(void* ptr, uint size): Commit memory.
vmem_physmem uint vmem_physmem(): Return amount of physical memory.
vmem_reserve void* vmem_reserve(void* ptr, uint size): Functions to manage allocating a single virtual address space.
vmem_reservesize void vmem_reservesize(uint* psize): Calculate the amount of memory to reserve, adjusting *psize downwards.
vmem_setfilesize void vmem_setfilesize(uint size): Set size of mapped file.
vmem_unmapfile void vmem_unmapfile(): Unmap previous file mapping.

Variables

_osfhnd void*[] _osfhnd;: Get file size of open file. Return -1L on error.
