File IO functions in DSP simulation

Started by January 9, 2007
It is amazing that the file IO subroutines still work in DSP simulation
even in JTAG emulation.
But when my programme becomes large, it seems that  fread and fwrite
functions have some problems. Sometimes, fread can not read data from
the file locating at the PC side, and sometimes fwrite can not write
data into the file.
Can anyone tell me what happens when I call fread and fwrite functions
in my dsp programme?
