Bfile_FindFirst_NON_SMEM

Synopsis #

Header: fxcg/file.h
Syscall index: 0x1DB6
Function signature: int Bfile_FindFirst_NON_SMEM(const unsigned short* pathname, int* FindHandle, const unsigned short* foundfile, file_type_t* fileinfo)

Initializes a search on a device other than the storage memory for a list of files and folders and retrieves info about each. Probably has no practical application on the Prizm, since there is no SD card slot and the main memory doesn’t count as a device (use the MCS syscalls instead).

Parameters #

const unsigned short* pathname - The 16 bit string containing the path of which to search (you may use one ‘*’ as a wildcard, ex: “\\crd0\*.g3a”). You must prefix the device identifier to the path, such as \\crd0\.\
int* FindHandle - Search handle. This must be closed using Bfile_FindClose when you’re done finding files.\
const unsigned short* foundfile - Will contain the file or folder name as a 16 bit string. Doesn’t contain the full path.\
file_type_t* fileinfo - Pointer to a file_info_t struct. The members of this struct are not used as documented on Bfile_FindFirst!

Returns #

0 on success, or a negative error code on failure.

Comments #

This syscall is probably useful on a system with SD card slot, for example a future model of the Prizm. However, there should be no need to use it directly, as syscall Bfile_FindFirst will automatically call this one when a device other than the storage memory is used.

Using Bfile functions while user timers are installed can cause SYSTEM ERRORs and other undefined behavior, especially with functions that change data on the file system. Make sure to stop and uninstall all timers before using Bfile functions (and optionally restore them later). See Incompatibility_between_Bfile_Syscalls_and_Timers for more information.
