xt_ff_dsv_line_read(3) Library Functions Manual xt_ff_dsv_line_read(3) NAME xt_ff_dsv_line_read() - Read a line of generic tabular data LIBRARY #include <xtend/ff-dsv.h> -lxtend SYNOPSIS int xt_ff_dsv_line_read(xt_ff_dsv_line_t *xt_ff_dsv_line, FILE *stream, const char *delims) ARGUMENTS xt_ff_dsv_line Pointer to a xt_ff_dsv_line_t structure to hold the fields stream FILE stream from which the line is read delims Array of acceptable delimiters DESCRIPTION Read a line of an arbitrary DSV file into a xt_ff_dsv_line_t object. Memory is allocated for the text of the fields, and it must be freed using fsv_line_free(3) before calling xt_ff_dsv_line_read(3) on the same object again. The xt_ff_dsv_line_t structure contains an array of strings, each hold- ing one field from the line, and an an array of delimiters, each hold- ing the character that ended the corresponding field. Note that each field could potentially end with a different delimiter, as multiple de- limiters can be specified. This function serves a purpose similar to the split() functions present in many languages. However, it does not need to read an entire line into a character array and then split the array. Instead, it separates fields as they are read from the input stream. RETURN VALUES Actual delimiter of last field (should be newline) EXAMPLES xt_ff_dsv_line_t *line = xt_ff_dsv_line_new(); while ( xt_ff_dsv_line_read(line, stdin, "\t") != EOF ) { xt_ff_dsv_line_write(line, stdout); xt_ff_dsv_line_free(line); } SEE ALSO xt_ff_dsv_line_new(3), xt_ff_dsv_line_free(3), xt_ff_dsv_line_read(3), xt_ff_dsv_line_write(3), xt_ff_dsv_line_copy(3), xt_ff_dsv_read_field(3), xt_ff_dsv_read_field_malloc(3), xt_ff_dsv_skip_field(3), xt_ff_dsv_skip_rest_of_line(3) xt_ff_dsv_line_read(3)
