Assuming the idea is to check the infile, the line needs to be:
if (psfinfo_in->channels != 2){
It is remarkable sometimes what a C compiler will accept.
The for loop over samples (which should not assume the read function
always returns the number of samples requested) should read:
for(i=0; i < count; i++)
not
for(i=0, i < BUFFRAMES; i++;)
One of those cases where we are asking the compiler to
"don't do what I say, do what I mean"!
Also, as the program reads mono in and writes stereo (I assume
duplicating samples), the loop body needs to be something like:
for(i=0; i < count; i++) {
out[i*2] = buffer[i];
out[i*2+1] = buffer[i];
}

(1)
You never open psf_out2 si writing to it will be a disaster.
Also it is safer to initialise psfinfo_out to zero
psfinfo_out= (SF_INFO *) calloc(1,sizeof(SF_INFO));
/////////////
// check if file is mono or stereo
if (!(psfinfo_out->channels = 2))
/* allocate buffer memory */
buffer = (float *) malloc(sizeof(float)*BUFFRAMES);
out = (float *) malloc(sizeof(float)*BUFFRAMES*2);
I think you mean
if (psfinfo_out->channels != 2) {
…
}
