should be specified. For example, @samp{odd:} is
interpreted as the file named @file{odd}.
@item main
Selects all functions named "main". Notice
that there may be multiple instances of the
same function name because some of the
definitions may be local (i.e., static).
Unless a function name is unique in a program,
you must use the colon notation explained
below to specify a function from a specific
source file. Sometimes, function names contain
dots. In such cases, it is necessar to
add a leading colon to the name. For example,
":.mul" selects function ".mul".
Selects all functions named @samp{main}.

Sometimes, function names contain dots. In such cases, it is necessar

function @samp{.mul}.
In some object file formats, symbols have a leading underscore. gprof
will normally not print these underscores. However, you must use the
underscore when you name a symbol in a symspec. You can use the
@code{nm} program to see whether symbols have underscores for the object
file format you are using.
@item main.c:main
Selects function "main" in file "main.c".
Selects function @samp{main} in file @file{main.c}.
@item main.c:134
Selects line 134 in file "main.c".
Selects line 134 in file @file{main.c}.
