xt_dsv_read_field_malloc(3) Library Functions Manual xt_dsv_read_field_malloc(3) NAME xt_dsv_read_field_malloc() - Read next field from tabular input, allocating memory as needed LIBRARY #include <xtend/dsv.h> -lxtend SYNOPSIS int xt_dsv_read_field_malloc(FILE *stream, char **buff, size_t *buff_size, const char *delims, size_t *len) ARGUMENTS stream FILE stream from which field is read buff Character buffer into which field is copied buff_size Size of the array passed to buff delims Array of characters that may serve as delimiters len Pointer to a variable which will receive the field length DESCRIPTION Read next delimiter-separated field from stream, allocating a buffer to fit in the fashion of strdup(3). The fields may be ended by any character in the string delims or by a newline ('\n'). If the delimiter ending a field is a space, then subsequence spaces are discarded, so that multiple space characters serve as a single delimiter. *buff_size indicates the size of the existing array, if one is already al- located. If *buff does not point to an allocated array, this should be 0, i.e. pass the address of a variable containing 0, not NULL. *buff_size will be updated if the array needs to be expanded to accommodate the new input. RETURN VALUES Delimiter ending the field (either a member of delim or newline) or XT_MAL- LOC_FAILED.
