You’re going to need fopen and fprintf, so correct usage will be:

FILE * pFile;
pFile = fopen ("asound.conf","w");
char *yourVariable; // Assign whatever you need
if (pFile!=NULL){
    fprintf(pFile, "pcm.!bluetooth ...\n\tdevide \"%s\"", yourVariable);
    fclose (pFile);
} else {
    printf( "Error opening file\n");
}
