Function Documentation

int is_image_ignored ( char const * name )

is_image_ignored - check if we must ignore this image

Parameters:

name

the name to check

Return true if the image should not be profiled

void opd_open_logfile ( void )

opd_open_logfile - open the log file

Open the logfile on stdout and stderr. This function assumes that 1 and 2 are the lowest close()d file descriptors. Failure to open on either descriptor is a fatal error.
