s32 FS_ReadFile( FSFile *p_file, void *dst, s32 len );
p_file | Address of the FSFile structure |
dst | Address of the storage destination buffer |
len | Byte length of data being read |
If the data is correctly read, it returns the number of bytes. Otherwise it returns a value of -1.
This function reads a specified size of data from the file pointer's current position. If the specified size exceeds the end of the file, it will read to the end of the file and return that size.
When using the ROM Archive
