linux - how to print just filename without using __FILE__ in C -

this question has reply here:

__file__ macro manipulation handling @ compile time 6 answers

i want print filename beingness used in project. if utilize __file__, prints entire path along file name long in case , disturbs log indents.

can please help how can print file name using mutual parameter across project.

in c code, might utilize instead of __file__ look basename(__file__); however, has disadvantage of calling basename @ every occurrence.

alternatively, compile path/foo.c command like

gcc -wall -c -g -dbase_file=\"foo\" path/foo.c

(you have generic make rule giving that)

then utilize base_file instead of __file__ in code.

with gcc, utilize __base_file__ instead of __file__

c linux
