.TH END 3 .SH NAME end, etext, edata \- last locations in program .SH SYNOPSIS .B extern end; .br .B extern etext; .br .B extern edata; .SH DESCRIPTION These names refer neither to routines nor to locations with interesting contents. The address of .I etext is the first address above the program text, .I edata above the initialized data region, and .I end above the uninitialized data region. .PP When execution begins, the program break coincides with .I end, but many functions reset the program break, among them the routines of .IR brk (2), .IR malloc (3), standard input/output .RI ( stdio (3)), the profile .RB ( \-p ) option of .IR cc (1), etc. The current value of the program break is reliably returned by `sbrk(0)', see .IR brk (2). .SH "SEE ALSO" brk(2), malloc(3)
