.SH NAME
copylist \- copy a file into memory
.SH SYNOPSIS
.LP
.nf
cc [ \fIflag\fR ... ] \fIfile\fR ... \fB-lgen\fR [ \fIlibrary\fR ... ]
#include <libgen.h>

\fBchar *\fR\fBcopylist\fR(\fBconst char *\fR\fIfilenm\fR, \fBoff_t *\fR\fIszptr\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBcopylist()\fR function copies a list of items from a file into freshly allocated memory,  replacing new-lines with null characters.  It expects two arguments: a pointer \fIfilenm\fR to the name of the file to be copied, and a pointer \fIszptr\fR to a variable where the size of the file will be stored.
.sp
.LP
Upon success, \fBcopylist()\fR returns a pointer to the memory allocated.  Otherwise it returns NULL if it has trouble finding the file, calling \fBmalloc()\fR, or reading the file.
.SH USAGE
.sp
.LP
The \fBcopylist()\fR function has a transitional interface for 64-bit file offsets. See \fBlf64\fR(5).
