.SH "NAME"
econf_errLocation \- retrieve the location of the last error

.SH "SYNOPSIS"

.sp
.ft B
.nf
#include <libeconf\&.h>
.fi
.ft
.sp

.BI "void econf_errLocation(char\ **" "filename" ", uint64_t\ *" "line_nr" ");"

.SH "DESCRIPTION"

.PP
\fBeconf_errLocation\fR retrieves the file path and line number where the last libeconf error occurred\&. This information is stored in thread\-local storage and is updated whenever a libeconf function encounters a parsing or processing error\&.

.PP
The \fIfilename\fR argument is a pointer to a string pointer\&. On return, \fBeconf_errLocation\fR sets this pointer to a newly allocated string containing the absolute path of the file where the error occurred\&. The caller is responsible for freeing this memory using
\fBfree\fR(3)\&.

.PP
The \fIline_nr\fR argument is a pointer to a 64\-bit unsigned integer\&. On return, it is set to the line number within the file where the error was detected\&.

.SH "RETURN VALUE"

.PP
This function does not return a value\&.

.SH "NOTES"

.PP
If no error has occurred, or if the error location is not available, \fI*filename\fR may be set to \fBNULL\fR and \fI*line_nr\fR to 0\&. Always check if \fI*filename\fR is not \fBNULL\fR before attempting to use or free it\&.
