Module fd_diagnostics 

Structs

FdTrackGuard

RAII scope guard that records FD growth/cleanup over a code path. Logs on creation/drop only when fd-track is enabled.

Functions

count_open_fds

Returns the number of currently open file descriptors for this process.

fds_since_baseline

Returns the number of file descriptors opened since the last call to set_fd_baseline. Negative values (FDs closed) are reported as 0.

list_open_fds

Returns a snapshot of all currently open file descriptors and what they point to (via readlink on Linux).

print_new_fds

Prints FDs present in after but not in before.

report_fd_count

Logs the current FD count snapshot with a label when fd-track is enabled.

set_fd_baseline

Sets the baseline FD count to the current value. Call this once at the start of a test or process to establish a reference point.
