Revision as of 23:05, 17 December 2010
Syscalls are OS functions exposed by Ndless to C and assembly programs. This article describes the syscalls currently available with Ndless 1.7.
Your help is needed to make this list grow to a full-fledged library. Try to find new syscalls, test them and share them for integration in Ndless.
Functions marked with (*) are available only if the program is linked against Newlib, i.e. when the nspire-ld switch -nostdlib is not used.

Nucleus
- int NU_Local_Control_Interrupts(int mask): sets the interrupt mask. Returns the previous mask.
- int NU_Current_Dir(const char *drive, char *path): fills in path with the full path name of the current working directory. Returns 0 on success. If drive is null or an invalid drive specifier the default drive is used.
- int NU_Get_First, struct dstat *statobj, const char * pattern): given a pattern which contains both a path specifier and a search pattern, fills in the structure at statobj with information about the file and sets up internal parts of statobj to supply appropriate information for calls to NU_Get_Next. Returns 0 if a match was found otherwise FALSE.
- int NU_Get_Next(struct dstat *statobj): given a pointer to a DSTAT structure that has been set up by a call to NU_Get_First(), searches for the next match of the original pattern in the original path. Returns 0 if found and updates statobj for subsequent calls to NU_Get_Next.
- void NU_Done(struct dstat *statobj): given a pointer to a DSTAT structure that has been set up by a call to NU_Get_First(), frees internal elements used by the statobj.
- NU_Set_Current_Dir(const char *name): Set the current working directory for a drive.
TI-Nspire GUI
- void ascii2utf16(void *buf, const char *str, int max_size): converts the ASCII string str to the UTF-8 string buf of size max_size.
- void show_dialog_box2(int winid, const char *utf8_title, const char *utf8_msg): displays a dialog box of title utf8_title containing utf8_msg. utf8_title and utf8_msg are C strings converted with ascii2utf16(). winid must be 0.
Miscellaneous
- int read_unaligned_longword(void *ptr)
- int read_unaligned_word(void *ptr)
